int t;

cin>>t;

while(t--){

long long int n,m,rev=0,rev1=0,n1,m1,s=0,r;

cin>>n>>m;

n1=n;m1=m;

while(n>0){

rev=rev*10+n%10;

n/=10;

}

while(m>0){

rev1=rev1*10+m%10;

m/=10;

}

s=rev+rev1;

long long int srev=0;

    while(s>0){

srev=srev*10+s%10;

s/=10;

}

cout<<srev<<endl;

}

return 0;

}
