WebJun 20, 2024 · (This is where your solution goes wrong.) The simplest way to do this is to exploit the implicit order of coins due to their array indices. We recursively find the number of ways to make change using coins i+1 and larger for the remaining part of the target value: V - N [i] * coins [i]. WebThe idea of the algorithm is to build the solution of the problem from top to bottom. It applies the idea described above. It use backtracking and cut the partial solutions in the recursive tree, which doesn't lead to a viable solution.

In this case, we keep the target value the same, but only consider coins with index greater than i. Namely, the number of ways to make change in this case is T(i+1,m). Since these cases are disjoint and exhaustive (either you put the ith coin in the solution or you don't!), we have that switch yuri
