Write a function named "indexed_list" that takes a list as a parameter. Your function will create a new array. Your function should loop through each index in the function's input and add that value to your new array. When the loop ends, the new array and function input should have the same length. Additionally, the new array's entry at index 0 would have the value 0, the entry at index 1 would have the value 1, and so on. The function should return the new array.
