2357 - Make Array Zero by Subtracting Equal Amounts.<p>Easy</p> <p>You are given a non-negative integer array <code>nums</code>. In one operation, you must:</p> <ul> <li>Choose a positive integer <code>x</code> such that <code>x</code> is less than or equal to the <strong>smallest non-zero</strong> element in <code>nums</code>.</li> <li>Subtract <code>x</code> from every <strong>positive</strong> element in <code>nums</code>.</li> </ul> <p>Return <em>the <strong>minimum</strong> number of operations to make every element in</em> <code>nums</code> <em>equal to</em> <code>0</code>.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> nums = [1,5,0,3,5]</p> <p><strong>Output:</strong> 3</p> <p><strong>Explanation:</strong></p> <p>In the first operation, choose x = 1. Now, nums = [0,4,0,2,4].</p> <p>In the second operation, choose x = 2. Now, nums = [0,2,0,0,2].</p> <p>In the third operation, choose x = 2. Now, nums = [0,0,0,0,0].</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> nums = [0]</p> <p><strong>Output:</strong> 0</p> <p><strong>Explanation:</strong> Each element in nums is already 0 so no operations are needed.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 100</code></li> <li><code>0 <= nums[i] <= 100</code></li> </ul>
