[BAEKJOON Online Judge + Node.js] 2292: Honeycomb

 

I did't use while loop that much so didn't come up what to do. While loop create a loop that execute a specific statement. So, the main point of this problem is "prevNum + max * 6"

input = 13, output = 3

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

let count = 1;

let max = 1;

// set the range

while (max < input) {

max += count * 6;

count++;

}

console.log(count);

// prevNum + count * 6

// 1 so +6 every loop!

// 2 - 7, 5

// 8 - 19, 11

// 20 - 37, 17

// 38 - 61, 23
