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, ['Y', '4091', 'A', 'D', 'Z', 'A', '9943', 'K', 'b', '5223', '7507', '2523', 'O', 'S', 'T', '2541', '4321', 'o', 'I', '161', '3113', '6889', 'p', '6509', 'v']
