Diagonal Difference

    You've actually got 3xN conditions, counting all your loops, but I like your thinking.

    Here's my solution from JavaScript:

    var n = parseInt(readLine());
var suma = 0, sumb = 0;
for(var i = 0; i < n; i++){
   var line = readLine().split(' ');
   suma += Number(line[i]);
   sumb += Number(line[n-i-1]);
}
console.log(Math.abs(sumb-suma));
