You are in charge of the cake for a child's birthday. You have decided the cake will have one candle for each year of their total age. They will only be able to blow out the tallest of the candles. Count how many candles are tallest.


candles = [4,4,1,3]

The maximum height candles are 4 units high. There are of 2 them, so return 2.

Function Description

Complete the function birthdayCakeCandles in the editor below.

birthdayCakeCandles has the following parameter(s):

    int candles[n]: the candle heights


    int: the number of candles that are tallest

Input Format 

The first line contains a single integer, n , the size of candles[i].
The second line contains  n space-separated integers, where each integer i describes the height of candles[i] .


1 <= n <= 10^5
1 <= candles[i] <= 10^7

Solution :


                            Solution in C :

In C :

int birthdayCakeCandles(int ar_count, int* ar) {
    int  max = ar[0], count = 0;
    for(int i=0;i<ar_count;i++)
        if(ar[i] > max)
                max  = ar[i];

    for(int i=0;i<ar_count;i++)
        if(ar[i] == max)

    return count;

In C ++:

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int main() {
    int N; cin>>N;
    int a[N];
    for(int i=0;i<N;i++) cin>>a[i];
    int biggest = 0;
    for(int i=0;i<N;i++) biggest = max(biggest, a[i]);
    int count = 0;
    for(int i=0;i<N;i++) if (a[i] == biggest) count++;
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */   
    return 0;

In Python3 :


In Java :

import java.util.*;

public class Solution {

    public static void main(String[] args) {
        Scanner in = new Scanner(;
        int n = in.nextInt();
        int max = 0;
        int sum = 0;
        int num;
        for(int i =0; i < n; i++){
            num = in.nextInt();
            if(num > max){
                sum = 1;
                max = num;
            }else if(num == max){

Find the Running Median

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.

Tieu owns a pizza restaurant and he manages it in his own way. While in a normal restaurant, a customer is served by following the first-come, first-served rule, Tieu simply minimizes the average waiting time of his customers. So he gets to decide who is served first, regardless of how sooner or later a person comes. Different kinds of pizzas take different amounts of time to cook. Also, once h
