Solution in JavaScript (judge verdict: Accepted)

var x = require('fs').readFileSync('/dev/stdin', 'utf8');
var lines = x.split(/\n/);
for (var i = 0; i < lines.length ; i++) {
  var arr = lines[i].split(/\s/).map(Number);
  if ((arr[0]==0)&&(arr[1]==0)) break;
  for (var j = 0; j < arr[0]; j++){
    for (var k = 0; k < arr[1]; k++) process.stdout.write("#");
    console.log();
  }
  console.log();
}
