Permutations and Combinations

Talk about permutations and combinations can be scary. I was in an interview a couple of years back, and one of the interviewers brought up this question about the difference between the two. Although, I was not being interviewed, I was baffled even while sitting on the side of the interviewers. Then, I found this brilliant article that explains the difference between the two. I wonder why I didn’t share it then and there. Please peruse.


Easy Permutations and Combinations
