<p>Given an integer array <code>nums</code>, your goal is to make all elements in <code>nums</code> equal. To complete one operation, follow these steps:</p>
|
|
|
|
<ol>
|
|
<li>Find the <strong>largest</strong> value in <code>nums</code>. Let its index be <code>i</code> (<strong>0-indexed</strong>) and its value be <code>largest</code>. If there are multiple elements with the largest value, pick the smallest <code>i</code>.</li>
|
|
<li>Find the <strong>next largest</strong> value in <code>nums</code> <strong>strictly smaller</strong> than <code>largest</code>. Let its value be <code>nextLargest</code>.</li>
|
|
<li>Reduce <code>nums[i]</code> to <code>nextLargest</code>.</li>
|
|
</ol>
|
|
|
|
<p>Return <em>the number of operations to make all elements in </em><code>nums</code><em> equal</em>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [5,1,3]
|
|
<strong>Output:</strong> 3
|
|
<strong>Explanation:</strong> It takes 3 operations to make all elements in nums equal:
|
|
1. largest = 5 at index 0. nextLargest = 3. Reduce nums[0] to 3. nums = [<u>3</u>,1,3].
|
|
2. largest = 3 at index 0. nextLargest = 1. Reduce nums[0] to 1. nums = [<u>1</u>,1,3].
|
|
3. largest = 3 at index 2. nextLargest = 1. Reduce nums[2] to 1. nums = [1,1,<u>1</u>].
|
|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,1,1]
|
|
<strong>Output:</strong> 0
|
|
<strong>Explanation:</strong> All elements in nums are already equal.
|
|
</pre>
|
|
|
|
<p><strong>Example 3:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,1,2,2,3]
|
|
<strong>Output:</strong> 4
|
|
<strong>Explanation:</strong> It takes 4 operations to make all elements in nums equal:
|
|
1. largest = 3 at index 4. nextLargest = 2. Reduce nums[4] to 2. nums = [1,1,2,2,<u>2</u>].
|
|
2. largest = 2 at index 2. nextLargest = 1. Reduce nums[2] to 1. nums = [1,1,<u>1</u>,2,2].
|
|
3. largest = 2 at index 3. nextLargest = 1. Reduce nums[3] to 1. nums = [1,1,1,<u>1</u>,2].
|
|
4. largest = 2 at index 4. nextLargest = 1. Reduce nums[4] to 1. nums = [1,1,1,1,<u>1</u>].
|
|
</pre>
|
|
|
|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= nums.length <= 5 * 10<sup>4</sup></code></li>
|
|
<li><code>1 <= nums[i] <= 5 * 10<sup>4</sup></code></li>
|
|
</ul>
