지식의모듈화

시간초과가 발생한다. let input =require('fs').readFileSync('./input.txt').toString().trim().split('\n'); let nums= input[1].split(' ').map(e=>Number(e)) // console.log(nums);//[ 3, 5, 2, 7 ] let ans=[]; ans[nums.length-1]=-1; for(let i= nums.length-2;i>=0;i--){ if(nums[i] nums[i]){ ans[i]=last; Stack.push(nums[i]); } else{ while( laststr+=(e+" ")); console.log(str);

1. 상기의 코드는 시간초과가 발생한다. let input =require('fs').readFileSync('/dev/stdin').toString().trim().split('\n'); input.shift(); let nums= input[0].split(' '); // console.log(nums);//[ 2, 4, -10, 4, -9 ] let obj={}; nums.forEach(e=>obj[e]=(obj[e]||0)+1); let keyarr= Object.keys(obj).map(e=>Number(e)); keyarr.sort((a,b)=>a-b); // console.log(keyarr) //[-10, -9, 2, 4 ] let str='' nums.forEach(e=>{ // cons..

let input =require('fs').readFileSync('/dev/stdin').toString().trim().split('\n').map(e=>Number(e)); let n =input.shift(); let sum=0; input.forEach(e=>sum+=e); let avg= Math.round(sum/n); if( avg===-0) avg=0; console.log(avg)//산술평균 input.sort((a,b)=>a-b); console.log(input[(1+n)/2-1])//중앙 let obj={}; input.forEach(e=>obj[e]=(obj[e]||0)+1); let max=0; let common=[]; for( key in obj){ if (max Numb..
