an initial screening call with a recruiter, followed by a technical phone screen with a hiring manager, and then a series of virtual interview rounds:

• coding challenges
• behavioral questions

focusing on assessing both technical skills and cultural fit for the role.

You are given an integer array arr.

We split arr into some number of chunks (i.e., partitions), and individually sort each chunk. After concatenating them, the result should equal the sorted array.

Return the largest number of chunks we can make to sort the array.
