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, 10, ['79', 'f', 'I', '4533', 'I', '459', 'a', '5689', 'x', '2037', 'l', '8545', 'y', 'a', 'V', '1807', 'l', '1225', 'q', 'd', 'g', '6649', '303', 'B', 'j', 'J', 'w', 'C', '4959', 'Q']
