HackerRank Viral Advertising problem solution YASH PAL, 31 July 2024 In this HackerRank Viral Advertising problem, you need to determine how many people have liked the ad by the end of a given day, beginning with launch day as day 1. Problem solution in Python programming. import math input_str = input() try: nbr = int(input_str) except: print("An exception occurred while parsing input as integer.") if nbr <= 0 or nbr >= 51: print("Bad input specified") result = 0 people = 5 for day in range(1, nbr + 1): half = math.floor(people / 2) result += half people = 3 * half print(result) Problem solution in Java Programming. import java.io.*; import java.util.*; public class Solution { public static void main(String[] args) { Scanner in = new Scanner(System.in); int n = in.nextInt(); int received = 5; int sum=0; while(n-- >0){ int remaining = received/2; sum+=remaining; received = remaining*3; } System.out.println(sum); } } Problem solution in C++ programming. #include <cmath> #include <cstdio> #include <vector> #include <iostream> #include <algorithm> using namespace std; int main() { /* Enter your code here. Read input from STDIN. Print output to STDOUT */ int n; cin>>n; int m = 5; int total; for(int i=0; i<n; ++i){ m = m/2; total += m; m *= 3; } cout<<total<<endl; return 0; } Problem solution in C programming. #include <stdio.h> #include <string.h> #include <math.h> #include <stdlib.h> int main() { int n,i,t1=0,t2=0,sum=0,m=5; scanf("%d",&n); for(i=0;i<n;i++) { t1 = m/2; m = t1*3; sum += t1; } printf("%d",sum); /* Enter your code here. Read input from STDIN. Print output to STDOUT */ return 0; } Problem solution in JavaScript programming. function processData(input) { var n = parseInt(input), result = 0; function totalLikes(people, n){ var liked = Math.floor(people / 2); result += liked; if(n > 1){ totalLikes(liked * 3, --n); } } totalLikes(5, n); console.log(result); } process.stdin.resume(); process.stdin.setEncoding("ascii"); _input = ""; process.stdin.on("data", function (input) { _input += input; }); process.stdin.on("end", function () { processData(_input); }); algorithm coding problems
