Tabulation vs Memoization for Backtracking solutions in Dynamic ...
Web6 feb. 2024 · Time complexity: O(2^max(m,n)) as the function is doing two recursive calls – lcs(i, j-1, 0) and lcs(i-1, j, 0) when characters at X[i-1] != Y[j-1]. So it will give a worst case time complexity as 2^N, where N = max(m, n), m and n is the length of X and Y string. Auxiliary Space: O(1): as the function call is not using any extra space (function is just … Web10 feb. 2024 · Tabulation: Known as the “bottom-up ” dynamic programming, usually the problem is solved in the direction of solving the base cases to the main problem.
