Part 1. 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 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.
Part 2. Example
6, 14, ['9545', '5185', '1667', 'w', 's', '9559', 'T', 'u', 'U', '6843', 'L', 'l', '6365', '7103', 'A', '2381', '5037', 'X', '4487', 'd']
Answer: 9559TuU6843Ll63657103
Explanation: Here, concatenating all the elements between the 6th element and 14th element gives '9559TuU6843Ll63657103'.
Part 3. Exercise
11, 23, ['a', '8217', '9527', '5779', 't', '9573', '9547', 'F', 'J', 'H', 'E', 'o', 'W', '2027', 'i', '7387', '5527', '8985', '4909', 'v', '2847', 'X', '3513', '4051', 'W']
