I was going through the solutions of various contestants for the problem 1287B. However, I was not able to understand the one that I hereby attach
https://codeforces.me/contest/1287/submission/68285034
There is a statement x[i]^= 66^t[i]; Now, I worked out what it does but , what I cannot get is how 66 was obtained? Is there a mathematical approach being followed or is it just by inspection?
((int)'S' ^ 'E' ^ 'T') = 66
