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, 6, ['u', 'e', 'P', 'i', 'L', 'f', '3077', '4619', '7149', 'K', 'd', 'f', '7203', '753', '7651', 'f', '8995', '4863', '4651', '8815', '7861', 'h']
