Definition: In this task, you are given inputs i, j, and A, where i and j are integers and A is a list. You need to find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output the resultant string. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j. Perform the operations in order, i.e., do not concatenate the elements and then reverse the string.
Input: 4, 7, ['B', 'w', 'M', 'y', 'G', '6857', '3001', 'q', '611', 'V', 'O', 'V', '1945', 'e', '6693', 'V', 'k', 'M', '3243', '1029', 'i', '397', 'r']
