翻译：对于M个查询，反转给定字符串的范围
In this problem, we will perform M reverse queries on the given string according to the array values.
The naïve approach to solving the problem is to reverse each string segment according to the given array value.
The optimized approach uses the logic that when we reverse the same substring two times, we get the original string.
Problem statement − We have given an alpha string containing the alphabetical characters. Also, we have given an arr[] array of size M containing the positive integers. We need to perform the M operations on the given string and return the final string.
In each operation, we need to take the arr[i] and reveres the substring arr[i] to N − arr[i] + 1.
