Webb2 mars 2024 · Consider any point in the staircase. Say we are on the ith step! Now we could have come to this stair either from the step behind or we can come from 2 steps behind. Those are the only possibilities. Also, it is quite obvious that we will have to pay for the floor we are on. Makes sense. Now think of the first initial step of the strategy. Webb4 aug. 2024 · Dynamic programming is nothing but recursion with memoization i.e. calculating and storing values that can be later accessed to solve subproblems that occur again, hence making your code faster and reducing the time complexity (computing CPU cycles are reduced).
