There are five student competitions in ABCDE, one for every two people, four for A, two for B, two for C, and how many games did E play?

1 or 3 games. Suppose A and BCDE both play one game, AD both play, and BC each has one game left, either two people compete with each other or both compete with E, suppose A and B play two games, or you can play one game each with CD, CE or DE. Compared with CD, ABD is finished, and C can only be compared with E. Compared with CE, c can also be compared with d or e. if compared with e, d can only be compared with e in the end; If you compare with d, it's all over. If you compare with DE, then C can only compare with E twice. If a and c are compared twice, the result is the same as above.

Well, after a rough calculation in my mind, I don't know right or wrong.
