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, 12, ['7521', 'j', 'n', '7821', 'u', '6533', '3643', '5049', 'c', 'Q', 'N', 'M', '51', 'f', 'B', '3457', '6463', '9023', 'b', 'a', '2023', 'T', 'q', 't', 't', '6177', 'J']
