NEED TO COMPLETE

You are given with an array. For each element present in the array your task is to print the next smallest than that number. If it is not smallest print -1

Sample Input :
7
10 7 9 3 2 1 15

Sample Output :
7 3 3 2 1 -1 -1

NOTE:

HOW TO BREAK THE ONCE I FIND THE SMALLEST NUMBER AFTER BREAK IT NEED TO CONTINUE FOR THE NEXT i VALUE 

const readline = require('readline');
const inp = readline.createInterface({
  input: process.stdin
});
const userInput = [];
inp.on("line", (data) => {
userInput.push(data);
});
inp.on("close", () =>
{var a =Number(userInput[0]);
 var inp =String(userInput[1]);
 var arr =inp.split(" ").map(val=>Number(val))
 var final=""
 for(i=0;i<a;i++)
 {
  for(j=1;j<a;j++) 
  {arr[i]>arr[j]
  final = final+arr[j]
  } //From this line
 
 }

 console.log(final);
 });
