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: 15, 26, ['7507', '2863', 'n', 'J', '9863', '2795', 'r', 'w', '6875', 'A', '4425', '6235', 'y', 'r', 't', 'j', '2665', 'D', '1813', 'K', '1491', '9205', 'l', 'D', '75', '8607', 'm', '233']
