In this task, you are given inputs 'i', 'j', and A, where 'i' and 'j' are integers and A is a list. A list is shown by two brackets and comma-separated numbers and characters inside, like ['1', '12', 'l']. You need to concatenate all elements of A from the ith element to the jth element, and then reverse the resulting 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 reverse first and then concatenate.

Input: Consider Input: 4, 7, ['6083', 'j', 'x', 'K', 'p', 'M', 'u', '4969', '2423', 'w', 'v', 'S', 'Y', 'v', '5165', 'Y', '3127', '79', '9755', 'Y', 'B', '7395', '6093', 'k', '2043', '6807']

Output: uMpK
