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: 10, 23, ['A', '5191', '3703', 'P', 'J', 'b', '5079', '4073', '8223', 'r', 'W', '6533', 'X', 't', 'Q', 'H', 'O', '1319', '1487', 'J', '4105', 'W', 'b', 'I', '3335', 'T', '29', 'U']
