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, 6, ['2063', '5453', '4399', 'X', 'T', 'K', 'J', '1231', 'P', '4685', '3521', 'W', 'c', '6787', 'q', 'Y', 'n', 'T', 'i', 'j', 'W', 'a', '975', 'j', '2259', 'm', '8385', '9927', 'p']
