You are given an array of integers and a target value. Your task is to write a function that returns the indices of the two numbers in the array that add up to the target. Assume that each input will have exactly one solution, and the same element cannot be used twice. For example, if the input array is [10, 20, 30, 40] and the target is 30, the function should return [0, 1] because 10 + 20 = 30. Return the indices as a list or array.
