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, 10, ['5207', 'U', 't', '7825', 'O', 'i', '3413', 'm', 'U', '789', 'Z', 'm', '9937', '6649', 'j', 'v', 'P', '4771', '7073', 'b', '5655', 'b', 'd', 'q', 'Q', '2659', 'Y']
