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: 15, 19, ['7497', '1363', 'u', 'D', '9263', 'E', 'H', 'F', 's', 'n', '4237', '131', 'c', '7047', 'y', 'w', 'g', 'i', 'T', '5211']
