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, 11, ['P', 'm', '145', '7391', 's', 'w', '9', '2895', '2951', '7129', '9029', 'B', 'M', 'p', '5157', '519', '9537', '1073', 'n']
