Decode the Coding Interview in C++: Real-World Examples

DIY: Combination Sum

Explore how to generate all unique combinations of integers from a given list that sum to a specific target. Learn to implement efficient backtracking algorithms in C++ to handle combination sum problems useful for coding interview preparation.

We'll cover the following...

Problem statement

We are given a list of distinct integers named contenders. Our goal is to determine all possible ways to pick any or all of these integers such that they add to the value target. The same number may be picked for addition an unlimited number of times. Two arrangements of numbers that add to target are unique if they differ by at least one number. If two ...
