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: 1, 4, ['y', 'P', 'U', 'C', '8473', 'S', '8255', '7537', '3187', 'J', 'c', 'U', 'P', '2575', '6497', '4103', '4425', 'E', 'v', '2629']
