# Intuition\n<!-- Describe your first thoughts on how to solve this problem. -->\nThe intuition behind the solution is to recursively flatten the given multi-dimensional array while considering the depth constraint.\n\n# Approach\n<!-- Describe your approach to solving the problem. -->\nThe approach used in the code is a depth-first traversal of the input array. For each element in the array, it checks if it is an array and if the current depth is greater than 0. If both conditions are met, the function recursively calls itself with the sub-array and reduces the depth by 1. Otherwise, it pushes the element into the result array.\n\n# Complexity\n- Time complexity:\n<!-- Add your time complexity here, e.g. $$O(n)$$ -->\nThe time complexity of the solution depends on the size of the input array and the depth. In the worst case, if the depth is equal to the maximum depth of the input array, the algorithm will visit all elements once. Therefore, the time complexity is O(N), where N is the total number of elements in the input array.\n\n- Space complexity:\n<!-- Add your space complexity here, e.g. $$O(n)$$ -->\nThe space complexity is also O(N) because the result array stores all the elements in the flattened array. Additionally, the recursive function calls occupy space on the call stack proportional to the depth of the array.\n\n# Code\n```\n/**\n * @param {any[]} arr\n * @param {number} depth\n * @return {any[]}\n */\nvar flat = function (arr, depth) {\n    var result = [];\n    \n    flatten(arr, depth, result);\n    \n    return result;\n};\n\nfunction flatten(arr, depth, result) {\n    for (var i = 0; i < arr.length; i++) {\n        if (Array.isArray(arr[i]) && depth > 0) {\n            flatten(arr[i], depth - 1, result);\n        } else {\n            result.push(arr[i]);\n        }\n    }\n}\n\n```
