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, 4, ['C', '2731', '6435', '5649', 'O', 'O', '3703', '4611', 'L', 'K', 'P', 'L', 'V', 'F', '8085', 'H', '933', '5013', 'N', '5205', 'X', 'I', '1971', 'C', 'E']
