I have used same code. I got WA on 45 test using "GNU C++20(64)" compiler but got accepted using "GNU C++17" compiler. Why?

"I have used same code"... but no?
vs
not same
I think this is not an issue. Becaues, find_set1(i) returns value of parent1[i].
parent1[i] stores the parent of ' i '
Did you read your own code?
find_set1changeparent1And your AC code surely works in C++20 too.

And your WA code surely too not works in C++17
