Tell us 4 input combinations that you will try and what is the expected outcome for those combinations for the Ringa Ringa Roses problem.

Question

Accepted Answer

The problem is about a game where kids recite a rhyme and one kid leaves the circle after each round until only one kid remains.

Try input combinations like (n=5, m=10), (n=8, m=15), (n=3, m=5), (n=6, m=12)
Expected outcome will be the number of rounds played and the kid who leaves the circle in each round
For example, for (n=5, m=10), the expected outcome could be 2 rounds played and kid 3 leaving in the first round and kid 1 leaving in the second round
