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: 7, 24, ['j', '7157', '4253', '5925', '6765', 'P', '3847', 'u', '1481', 'Q', '5509', '4831', 'q', 'A', 'm', '729', '4437', '7991', 'f', 'D', '9603', 'n', '4955', 'a', 'I', '29']
