-/**
- * 405. Convert a Number to Hexadecimal
-
- Given an integer, write an algorithm to convert it to hexadecimal. For negative integer, two’s complement method is used.
-
- Note:
-
- All letters in hexadecimal (a-f) must be in lowercase.
- The hexadecimal string must not contain extra leading 0s.
- If the number is zero, it is represented by a single zero character '0';
- otherwise, the first character in the hexadecimal string will not be the zero character.
- The given number is guaranteed to fit within the range of a 32-bit signed integer.
- You must not use any method provided by the library which converts/formats the number to hex directly.
-
- Example 1:
- Input:
- 26
-
- Output:
- "1a"
-
- Example 2:
- Input:
- -1
-
- Output:
- "ffffffff"
