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: 15, 25, ['1019', '7495', 'y', '4791', 'f', '2967', 'P', 'C', 'z', 'y', '8971', '8439', 'v', 'j', 'h', '459', 'v', '981', '5663', 'y', 'J', 'V', 'G', 'f', 'P']
