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: 11, 19, ['6555', '3635', '6827', '5177', '7387', 'J', 'Z', '5139', '6211', 'P', '6329', '2175', '5779', 's', 'i', 'G', 'I', 'v', 'x', 'Q', '2145', 'm', '8157', 'J', '3563', 'Y', 't']
