Mark was updating the company’s internal reward system to help teams split their quarterly bonus credits into balanced groups. He needed a way to identify every unique combination of four individual contribution scores that, when added together, perfectly matched the total budget allocated for a team event. Eva suggested that the results must only show unique sets to avoid repetitive planning, so if the available scores were 1, 0, -1, 0, -2, and 2 with a budget of 0, the tool should suggest sets like -2, -1, 1, and 2. Lena volunteered to build this utility so that managers could quickly see all the possible ways to group their staff for the upcoming retreat.
