Solution in JavaScript (judge verdict: WA: Presentation Error)

const input = require('fs').readFileSync('/dev/stdin', 'utf8').split('\n');
console.log(input.map(function(x) {
  const arr = x.split(' ').map(Number);
  return arr[0] == 0 ? '' : function(h, w) {
    return Array(h + 1).join(Array(w + 1).join('#').concat('\n'));
  }(arr[0], arr[1]);
}).join('\n').trim());
