Well, there's only two numbers in the input. For some reason you're using while, and for some reason it leads to infinite cycle apparently. Try to replace your while with if.
Also, you assume there's exactly 10 cans total. This is not true. The task says "no more than 10".

while becomes endless because of mistake:
Current state: while(scanf("%d %d",&a,&b)!=EOF && a<11 || b<11){
Should be: while(scanf("%d %d",&a,&b)!=EOF && (a<11 || b<11)){
