For k = 2 answer is the second element which is 13. - * Notice that 12 and 13 have the same power value and we sorted them in ascending order. Same for 14 and 15. - * - * Example 2: - * Input: lo = 1, hi = 1, k = 1 - * Output: 1 - * - * Example 3: - * Input: lo = 7, hi = 11, k = 4 - * Output: 7 - * Explanation: The power array corresponding to the interval [7, 8, 9, 10, 11] is [16, 3, 19, 6, 14]. - * The interval sorted by power is [8, 10, 11, 7, 9]. - * The fourth number in the sorted array is 7. - * - * Example 4: - * Input: lo = 10, hi = 20, k = 5 - * Output: 13 - * - * Example 5: - * Input: lo = 1, hi = 1000, k = 777 - * Output: 570 - * - * Constraints: - * 1 <= lo <= hi <= 1000 - * 1 <= k <= hi - lo + 1 - * */ public class _1387 { public static class Solution1 { public int getKth(int lo, int hi, int k) { From d948bb6f0f13122c5d7df28bde6cab63d407ca9c Mon Sep 17 00:00:00 2001 From: Fisher Coder Date: Sat, 14 Nov 2020 09:50:50 -0800 Subject: [PATCH 0086/1691] add 1652 --- README.md | 1 + .../java/com/fishercoder/solutions/_1652.java | 39 +++++++++++++++++ src/test/java/com/fishercoder/_1652Test.java | 42 +++++++++++++++++++ 3 files changed, 82 insertions(+) create mode 100644 src/main/java/com/fishercoder/solutions/_1652.java create mode 100644 src/test/java/com/fishercoder/_1652Test.java diff --git a/README.md b/README.md index 5c624c4386..524ce62555 100644 --- a/README.md +++ b/README.md @@ -8,6 +8,7 @@ _If you like this project, please leave me a star._ ★ | # | Title | Solutions | Video | Difficulty | Tag |-----|----------------|---------------|--------|-------------|------------- +|1652|[Defuse the Bomb](https://leetcode.com/problems/defuse-the-bomb/)|[Solution](../master/src/main/java/com/fishercoder/solutions/_1652.java) ||Easy|Array| |1640|[Check Array Formation Through Concatenation](https://leetcode.com/problems/check-array-formation-through-concatenation/)|[Solution](../master/src/main/java/com/fishercoder/solutions/_1640.java) ||Easy|Array, Sort| |1637|[Widest Vertical Area Between Two Points Containing No Points](https://leetcode.com/problems/widest-vertical-area-between-two-points-containing-no-points/)|[Javascript](./javascript/_1637.js)| | Medium | Sort | |1636|[Sort Array by Increasing Frequency](https://leetcode.com/problems/sort-array-by-increasing-frequency/)|[Solution](../master/src/main/java/com/fishercoder/solutions/_1636.java) ||Easy|Array, Sort| diff --git a/src/main/java/com/fishercoder/solutions/_1652.java b/src/main/java/com/fishercoder/solutions/_1652.java new file mode 100644 index 0000000000..8d9cf9c975 --- /dev/null +++ b/src/main/java/com/fishercoder/solutions/_1652.java @@ -0,0 +1,39 @@ +package com.fishercoder.solutions;

Count Primes - * - * Description: - - Count the number of prime numbers less than a non-negative number, n. - - Hint: - - Let's start with a isPrime function. To determine if a number is prime, we need to check if it is not divisible by any number less than n. - The runtime complexity of isPrime function would be O(n) and hence counting the total prime numbers up to n would be O(n2). Could we do better? - - As we know the number must not be divisible by any number > n / 2, - we can immediately cut the total iterations half by dividing only up to n / 2. Could we still do better? - - Let's write down all of 12's factors: - - 2 × 6 = 12 - 3 × 4 = 12 - 4 × 3 = 12 - 6 × 2 = 12 - As you can see, calculations of 4 × 3 and 6 × 2 are not necessary. Therefore, we only need to consider factors up to √n because, - if n is divisible by some number p, then n = p × q and since p ≤ q, we could derive that p ≤ √n. - - Our total runtime has now improved to O(n1.5), which is slightly better. Is there a faster approach? - - public int countPrimes(int n) { - int count = 0; - for (int i = 1; i < n; i++) { - if (isPrime(i)) count++; - } - return count; - } - - private boolean isPrime(int num) { - if (num <= 1) return false; - // Loop's ending condition is i * i <= num instead of i <= sqrt(num) - // to avoid repeatedly calling an expensive function sqrt(). - for (int i = 2; i * i <= num; i++) { - if (num % i == 0) return false; - } - return true; - } - - The Sieve of Eratosthenes is one of the most efficient ways to find all prime numbers up to n. - But don't let that name scare you, I promise that the concept is surprisingly simple. - - Sieve of Eratosthenes: algorithm steps for primes below 121. "Sieve of Eratosthenes Animation" by SKopp is licensed under CC BY 2.0. - We start off with a table of n numbers. Let's look at the first number, 2. We know all multiples of 2 must not be primes, so we mark - them off as non-primes. Then we look at the next number, 3. Similarly, all multiples of 3 such as 3 × 2 = 6, 3 × 3 = 9, ... must not - be primes, so we mark them off as well. Now we look at the next number, 4, which was already marked off. - What does this tell you? Should you mark off all multiples of 4 as well? - 4 is not a prime because it is divisible by 2, which means all multiples of 4 must also be divisible by 2 and were already marked off. - So we can skip 4 immediately and go to the next number, 5. - Now, all multiples of 5 such as 5 × 2 = 10, 5 × 3 = 15, 5 × 4 = 20, 5 × 5 = 25, ... can be marked off. - There is a slight optimization here, we do not need to start from 5 × 2 = 10. Where should we start marking off? - - In fact, we can mark off multiples of 5 starting at 5 × 5 = 25, because 5 × 2 = 10 was already marked off by multiple of 2, - similarly 5 × 3 = 15 was already marked off by multiple of 3. - Therefore, if the current number is p, we can always mark off multiples of p starting at p2, then in increments of p: p2 + p, p2 + 2p, ... - Now what should be the terminating loop condition? - - It is easy to say that the terminating loop condition is p < n, which is certainly correct but not efficient. Do you still remember Hint #3? - Yes, the terminating loop condition can be p < √n, as all non-primes ≥ √n must have already been marked off. When the loop terminates, - all the numbers in the table that are non-marked are prime. - - The Sieve of Eratosthenes uses an extra O(n) memory and its runtime complexity is O(n log log n). - For the more mathematically inclined readers, you can read more about its algorithm complexity on Wikipedia. - - public int countPrimes(int n) { - boolean[] isPrime = new boolean[n];

If the file content is very large (GB level), how will you modify your solution? - * A: We'll fist map all files according to their sizes, since files with different sizes are guaranteed to be different, then - * we can hash a small part of the files using MD5, SHA256, etc. Only when their md5 or sha256 is the same, we'll compare the contents byte by byte. - * - * 3. If you can only read the file by 1kb each time, how will you modify your solution? - * A: This is not going to change the solution, we can hash this 1kb chunk, and then also only compare byte by byte when it's necessary. - * - * 4. What is the time complexity of your modified solution? What is the most time consuming part and memory consuming part of it? How to optimize? - * A: O(n^2*k), in the worst time, we'll have to compare the file with every other file, k is the length of the file. - * Comparing the file (by size, by hash and eventually byte by byte) is the most time consuming part. - * Generating hash for every file will be the most memory consuming part. - * - * 5. How to make sure the duplicated files you find are not false positive? - * A: Size comparision, hash detection, byte by byte check, etc. will pretty sure to rule out false positive. - * */ - } From 03aa4e5a51a81fb3857e0c30c310efd8e35565af Mon Sep 17 00:00:00 2001 From: Fisher Coder Date: Wed, 19 May 2021 07:23:18 -0700 Subject: [PATCH 0432/1691] add a test for 462 --- src/test/java/com/fishercoder/_462Test.java | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/test/java/com/fishercoder/_462Test.java b/src/test/java/com/fishercoder/_462Test.java index 5b4942665b..7dbc7c63eb 100644 --- a/src/test/java/com/fishercoder/_462Test.java +++ b/src/test/java/com/fishercoder/_462Test.java @@ -19,4 +19,9 @@ public void test1() { assertEquals(2, solution1.minMoves2(new int[]{1, 2, 3}));

Often, people use the words "tabulation" and "dynamic programming" interchangeably. + *
