const fs = require('fs');
const input = fs.readFileSync("./dev/stdin").toString().trim().split("\n").map(v=>v.split(' ').map(x=>+x)); 
let answer = 0;
const N = +input[0][0];
const A = input[1].sort((a,b)=>{return a-b});
const B = input[2].sort((a,b)=>{return b-a});

for(let i = 0; i<N; i++){
  answer+=A[i]*B[i]
}

console.log(answer)
