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, 15, ['g', '3347', '89', 'A', '9417', '345', '5487', '1351', '4955', '8909', '5757', 'q', '8963', 'u', 'x', 't', 'a', 't', 'v', 'w', '8023', '7359', 'X', '5013', 'K', '4175', '9599', '7743', '8137', 'W']
