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: 3, 6, ['I', '5395', '6949', 'k', 'P', '5211', 's', 'r', 's', 'f', '2295', 'q', 'e', '8851', '4171', 'l', 'a', 'G', 'r', '5275', 'M', '9825', '351', 't', 'z', '4381', '9049', '9303']
