Solution in JavaScript (node.js v5.12) (judge verdict: Wrong Answer)

function Main(input){
    input = input.split('\n');
    var a = input.shift().split(' ');
    input.unshift(a[1]);
    input.unshift(a[0]);
    console.log(input);
    
    var h = Number(input[0]);
    var w = Number(input[1]);

    var igeta = '';
    for(i = 0; i < w + 2;i++) {
        igeta += '#';
    }
    console.log(igeta);

    for(i = 2; i < h + 2;i++) {
        console.log('#' + input[i] + '#');
    }

    console.log(igeta);
  }
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
