Army_1(20) > Army_2(21) but Army_1(3)>Army_2(2)?

I finisged coding in Visual Studio output was 'false' and it's right but when I checked code on the site for solve this mission right output was 'true' but how 20 warriors can win 21 warriors? okay I considered just change output, then output == true , and the next check was 3 warriors vs 2 warriors and right solution must output 'false' :/ ? This game joking on me or it's bug? Thanks
