Web Reference: Flatten Deeply Nested Array. Given a multi-dimensional array arr and a depth n, return a flattened version of that array. A multi-dimensional array is a recursive data structure that contains integers or other multi-dimensional arrays. When we encounter an array element while iterating through the input, we need to decide whether to unwrap it or keep it as is. This decision depends on how many levels deep we're allowed to flatten (the value of n). Think of n as a "budget" for how many levels we can unwrap. The solution uses a recursive helper function that takes the current array and the current depth. For each element in the array, if it is not an array, it is added directly to the result.
