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.

Example Input: 4, 12, ['8125', 'K', 'W', '8269', '5965', '7005', 'P', 'K', '5753', 'S', '1117', '3797', 'E', 'j']
