Mergesort is also a divide and conquer algorithm. It continuously divides an array into two halves, recurses on both the left subarray and right subarray and then merges the two sorted halves Stable: Yes Time C
Implement pow(x,y) using divide and conquer approach. Try implementing it in O(logn) pow.cpp Calculate factorial of large number, say 100 (it will have 158 digits) factorial_of_large_num.cpp Generate all possible words from a number entered on a traditional mobile keypad phone_digits.cpp ...
On drawing a recursion tree for the above solution, we can easily see that each subproblem gets repeated several times. The problem satisfies bothoptimal substructureandoverlapping subproblemsproperties of dynamic programming, so the subproblem solutions can be derived using memoization or in a bottom-u...
