My friend the_hyp0cr1t3 and I came across this weird behaviour which we can't seem to explain.

The submissions 121761224 and 121761200 are identical, yet the former (submitted in C++17) gets accepted and the latter (submitted in C++14) gets WA on test 1.

After an hour of debugging, we managed to get it accepted in C++14 (121761314) with the following change in the code:

WA (C++14)
AC (C++14)

We would appreciate if someone could explain why something like a = b = c; and a = c; b = a; seem to produce different results.
