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: 7, 14, ['9349', 'O', 'j', '1971', '3367', '7607', '5989', 'Y', 'T', '3473', '3523', '2611', '8897', '8063', '3651']
