1149번: RGB거리

const fs = require('fs');
const [n, ...arr] = fs.readFileSync("/dev/stdin").toString().trim().split("\n");

const N = +n;
let dp = arr.map(v => v.split(' ').map(v => +v))



for (let i = 1; i < N; i++) {
  dp[i][0] += Math.min(dp[i - 1][1], dp[i - 1][2])
  dp[i][1] += Math.min(dp[i - 1][0], dp[i - 1][2])
  dp[i][2] += Math.min(dp[i - 1][0], dp[i - 1][1])
}

const answer = Math.min(...dp[N - 1]);

console.log(answer);
