In the end, we copy the rest of the elements from the foo or the bar array. So the time complexity becomes O (fooLength + barLength). We've used an auxiliary array to obtain the result. So the space complexity is also O (fooLength + barLength). 6. Conclusion how to use day old white rice

"WebThe above approach reduces the time complexity to O (n.log (k)) but takes O (k) extra space for the heap. We can solve this problem in constant space using Divide and Conquer. We already know that two linked lists can be merged in O (n) time and O (1) space (For arrays, O (n) space is required). " - Merging two sorted arrays time complexity
