let fs = require('fs'); let input = fs.readFileSync('/dev/stdin').toString().split('\n'); let count = input[0]; let numbers = []; for (let i = 1; i < input.length; i++) { if (input[i] !== '') { numbers.push(input[i].split(' ')); } } for (let i = 0; i < numbers.length; i++){ let num1 = Number(numbers[i][0]); let num2 = Number(numbers[i][1]); console.log(num1 + num2); }
