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, 10, ['7521', 'j', '8589', 'C', '9565', 'c', '2841', '9307', '1695', '3449', '4883', '6613', 'q', '5077', '5647', '8773', 'Q', 'd', 's', 'H', 'm']
