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, 17, ['A', 'b', 'j', '4655', 'U', '2389', '6143', '6841', 'B', '1035', '2153', '5781', 'b', '9851', '1265', 'n', '4139', 'E', '4029', 'z', '8219', '1839', 'L', '185', 'S', '6969', '4195', 'm']
