Max Chunks To Make Sorted</a></h2><h3>Medium</h3><hr><div><p>You are given an integer array <code>arr</code> of length <code>n</code> that represents a permutation of the integers in the range <code>[0, n - 1]</code>.</p> |
| 2 | + |
| 3 | +<p>We split <code>arr</code> into some number of <strong>chunks</strong> (i.e., partitions), and individually sort each chunk. After concatenating them, the result should equal the sorted array.</p> |
| 4 | + |
| 5 | +<p>Return <em>the largest number of chunks we can make to sort the array</em>.</p> |

| 9 | + |
| 10 | +<pre><strong>Input:</strong> arr = [4,3,2,1,0] |
| 11 | +<strong>Output:</strong> 1 |
| 12 | +<strong>Explanation:</strong> |
| 13 | +Splitting into two or more chunks will not return the required result. |
| 14 | +For example, splitting into [4, 3], [2, 1, 0] will result in [3, 4, 0, 1, 2], which isn't sorted. |

| 18 | + |
| 19 | +<pre><strong>Input:</strong> arr = [1,0,2,3,4] |
| 20 | +<strong>Output:</strong> 4 |
| 21 | +<strong>Explanation:</strong> |
| 22 | +We can split into two chunks, such as [1, 0], [2, 3, 4]. |
| 23 | +However, splitting into [1, 0], [2], [3], [4] is the highest number of chunks possible. |
