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

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=i+1;j<a;j++)  
{  if(arr[i]>arr[j])
  {final = final+arr[j]
  break}
   if(!arr[i]>arr[j])
  {final = final+"-1"
  break}
  
  }
  
 }
 
 console.log(final);
 });
