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: 12, 17, ['7455', '393', 'o', '2171', 'Q', 'i', 'Y', '873', 'm', 'N', '397', '489', 'A', 'v', 'T', 'A', '9487', 'm', 'Z', 'Z', 'G', '9385', 'S', 'J']
