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: 1, 14, ['M', 'P', '4301', '519', 'T', '9875', '4475', '9039', '2931', '4731', 'v', 'v', '7051', 'H', 'M']
