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

var lines = [];
var readline = require('readline');

var rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

rl.on('line', function(input) {
    lines.push(input);
});

rl.on('close', function() {
    var inputsAsArr = lines[0].split(' ');
    var sideA = inputsAsArr[0];
    var sideB = inputsAsArr[1];
    var sideC = inputsAsArr[2];

    var outputStr = (sideA === sideB && sideA === sideC && sideB === sideC) ? 'Yes' : 'No';
    console.log(outputStr);
});
