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: 12, 24, ['7445', '8989', 'A', 't', 'g', 'J', '6035', 'l', 'u', 'L', 'r', '9277', '5299', '5379', '5653', '781', 'X', 'a', '4639', '3229', 'D', '4993', 'V', '6719', 'x']
