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: Consider Input: 6, 10, ['A', '2605', '2029', 'e', 'j', 'P', '5369', '1263', '2071', 'u', '3793', '6137', 'h', '6993']

Output: u207112635369P
