<h2><a href="https://leetcode.com/problems/zero-array-transformation-i/">3355. Zero Array Transformation I</a></h2><h3>Medium</h3><hr><div><p>You are given an integer array <code>nums</code> of length <code>n</code> and a 2D array <code>queries</code>, where <code>queries[i] = [l_i, r_i]</code>.</p>

<p>For each <code>queries[i]</code>:</p>

<ul>

<li>Select a subset of indices within the range <code>[l_i, r_i]</code> in <code>nums</code>.</li>

<li>Decrement the values at the selected indices by 1.</li>

</ul>

<p>A <strong>Zero Array</strong> is an array where all elements are equal to 0.</p>

<p>Return <code>true</code> if it is <em>possible</em> to transform <code>nums</code> into a <strong>Zero Array </strong>after processing all the queries sequentially, otherwise return <code>false</code>.</p>

<p>A <strong>subset</strong> of an array is a selection of elements (possibly none) of the array.</p>

<div class="example-block">

<p><strong>Input:</strong> <span class="example-io">nums = [1,0,1], queries = [[0,2]]</span></p>

<p><strong>Output:</strong> <span class="example-io">true</span></p>

<p><strong>Explanation:</strong></p>

<ul>

<li><strong>For i = 0:</strong>

<ul>

<li>Select the subset of indices as <code>[0, 2]</code> and decrement the values at these indices by 1.</li>

<li>The array will become <code>[0, 0, 0]</code>, which is a Zero Array.</li>

</ul>

<p><strong>Input:</strong> <span class="example-io">nums = [4,3,2,1], queries = [[1,3],[0,2]]</span></p>

<p><strong>Output:</strong> <span class="example-io">false</span></p>

<p><strong>Explanation:</strong></p>

<ul>

<li><strong>For i = 0:</strong>

<ul>

<li>Select the subset of indices as <code>[1, 2, 3]</code> and decrement the values at these indices by 1.</li>

<li>The array will become <code>[4, 2, 1, 0]</code>.</li>

</ul>

</li>

<li><strong>For i = 1:</strong>

<ul>

<li>Select the subset of indices as <code>[0, 1, 2]</code> and decrement the values at these indices by 1.</li>

<li>The array will become <code>[3, 1, 0, 0]</code>, which is not a Zero Array.</li>
