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, 15, ['R', 'I', 'l', 'P', '7101', 'E', '3569', 'p', '2645', 'v', '7805', 'Z', 'M', '6191', 'Z', '2375', 'd', 's', '6995', 'E', '8361', 'm', 'l', '7845', '213', '6123']
