Factorial function in C++ with Tail Recursion - Stack Overflow
Web5 Dec 2024 · Tail recursion is basically when: there is only a single recursive call that call is the last statement in the function And it’s not “better”, except in the sense that a good compiler can remove the recursion, transforming it into a loop. This may be faster and will certainly save on stack usage. The GCC compiler can do this optimisation. anon WebHow recursion works in C++ programming The recursion continues until some condition is met. To prevent infinite recursion, if...else statement (or similar approach) can be used where one branch makes the recursive call and the other doesn't.

Basically, you start with the full set of possible objects. For each object you get its value and create the subproblem excluding that object and with the available max weight reduced by the excluded object's weight.
