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: 10, 14, ['S', 'n', '943', 'k', '6089', 'Z', '3561', '3807', 'l', '8521', '781', 'A', '259', 'J', 'w', '7283', '9545', '7659']
