Where is mine failing? https://www.codechef.com/viewsolution/26747280

Can help me out too? https://www.codechef.com/viewsolution/26744112

My logic was

If A==B==0 AND C%2!=0 then [NO]
If A==C==0 AND B%2!=0 then [NO]
If B==C==0 AND A%2!=0 then [NO]

If A==0 && Bx2!=Cx3 then [NO]
If B==0 && A!=Cx3 then [NO]
If C==0 && A!=Bx2 then [NO]

if ((A+B*2+C)%2!=0) then [NO]

For everything else(i.e, all the 'if ’ conditions were evaluated to false) [YES]

Thank you soo much

I really wonder how to get to know my wrong answers I really struggle with that
