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: 5, 15, ['Q', '8059', 'K', '1359', 'A', '6481', 'r', '461', '5799', 'w', 's', '7847', '501', '3021', 'E', '3099', 'I', '2825', 'T', 'F', 's', '9953', '9873', '9445', 't', '9533']
