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: 18, 24, ['k', 'z', '9825', 'M', 'y', 'c', 'f', '1437', '4113', '8079', '7575', 'y', '731', 'c', '5691', 'I', 'a', 'u', 'f', 'n', '7263', 'p', '2079', 'm']
