Solution in JavaScript (judge verdict: Accepted)

var reader = require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
});
reader.on('line', function (line) {
  var i,j,result;
  var a = line.split(' ');
  var b = parseInt(a[0],10);
  var c = parseInt(a[1],10);
  if(!b && !c)
    process.exit();
  for(i=0;i<b;i++){
    result="";
    for(j=0;j<c;j++)
      result += "#";
    console.log(result);
  }
  console.log("");
});
process.stdin.on('end', function () {
});
