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, 17, ['1779', 'd', 'z', 'P', 'J', '409', 'f', 'q', '5047', 'Q', 'L', '7547', '6061', 'f', 'Q', 'H', 'v', '4253', '5537', '9975', '3775', 'f', '925', '5995', 'M', '8487', '4219']
