Pusheen recently got her report card back! Pusheen took two classes last semester, CS452 and PHIL145. She was rather burnt out from all the critical thinking and real-time programming that she had to do, so she needs your help to figure out which one she did better in.
~0 \le A \le 100~
~0 \le B \le 100~
In tests worth 14 marks, ~A = B~.
The first line of input contains a single integer, ~A~, Pusheen's mark in CS452.
The second line of input contains a single integer, ~B~, Pusheen's mark in PHIL145.
Output, on a single line, which course Pusheen did better in. If she did equally well in both courses, do not output anything.
Pusheen was really good at real-time programming but clearly had problems with critical thinking, so she got a 100 in CS452 and a 0 in PHIL145, and thus did better in CS452.
