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: 7, 13, ['J', '5985', 'B', '2585', '6833', '579', '7951', '2197', 'n', '3779', '7693', 'b', 'd', '5985', '4305', 't', 'e', 'A', 'n', '3801', '4679', 'T', '1069', 'V']
