Given the  for each individual candle, find and print the number of candles she can successfully blow out.

The first line contains a single integer, , denoting the number of candles on the cake.
The second line contains  space-separated integers, where each integer  describes the height of candle .

Constraints

Output Format

Print the number of candles Colleen blows out on a new line.

2

Explanation 0

We have one candle of height , one candle of height , and two candles of height . Colleen only blows out the tallest candles, meaning the candles where . Because there are  such candles, we print  on a new line.

Solution Answer

process.stdin.resume();
process.stdin.setEncoding('ascii');

var input_stdin = "";
var input_stdin_array = "";
var input_currentline = 0;

process.stdin.on('data', function (data) {
    input_stdin += data;
});

process.stdin.on('end', function () {
    input_stdin_array = input_stdin.split("\n");
    main();    
});

function readLine() {
    return input_stdin_array[input_currentline++];
}

/////////////// ignore above this line ////////////////////

function birthdayCakeCandles(n, ar) {
   
   var max=ar[0];
   var num=1;
 for (var i=1;i<n; i++){
   if (ar[i]>max){ 
      max=ar[i];
     num=1;
   }
   else if (ar[i]==max) num++;
   }
  return num;
    
}

function main() {
    var n = parseInt(readLine());
    ar = readLine().split(' ');
    ar = ar.map(Number);
    var result = birthdayCakeCandles(n, ar);
    process.stdout.write("" + result + "\n");
