Two methods to solve the problem of “Finding multiple numbers whose sum is a fixed value”, and the expansion of the 01 knapsack problem

I believe everyone has done the problem of Finding two numbers whose sum is a constant value, but what if we change it to Finding multiple numbers whose sum is a constant value Woolen cloth? Title description Input two integers n and sum, randomly pick a few numbers from the sequence 1, 2, 3…n so […]
