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, 15, ['T', 'y', 'y', '2159', '4429', '2621', '4061', '8923', 's', '3423', '6339', 'M', 'F', '4095', '6827', 'Z', '6937', 'W', '259', '5419', 'I', '1033', '4907', '3675', '4611', 'u', 'v', '113']
