3052 - Rest JS

https://www.acmicpc.net/problem/3052

 

My attempt

const input = require('fs').readFileSync('/dev/stdin').toString().split('\n');

const arr = [39,40,41,42,43,44,82,83,84,85];

const newArr = [];

for(let i=0; i< input.length; i++) {

const rest = (Number(input[i])%42);

newArr.push(rest)

}

let set1 = new Set(newArr);

console.log(set1.size);

This site might not accept Set syntax yet. 

Others 

const input = require("fs").readFileSync("/dev/stdin").toString().split("\n");

const userNum = [];

input.forEach((x) => {

const num = x % 42;

if (userNum.indexOf(num) === -1) {

userNum.push(num);

}

});

console.log(userNum.length);
