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: 11, 15, ['5679', '6217', '1403', '5841', '4699', '1865', '6833', 'M', '8499', 'I', 'M', 'J', 'Q', 't', '9845', '6447', 'v', '8499', '6327', '5445']
