Teacher: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 concatenate all elements of A from the ith element to the jth element, and print 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.
Teacher: Now, understand the problem? Solve this instance: 6, 7, ['o', '4199', 'n', 'A', 'q', '7697', 'Q', 'A', 'Z', 'C', 'K', '4011', '4751', 'W', 'i', '3255', '1449', 'B', 'z', '8747']
