    Here is my c++ solution, you can watch the explanation here : https://youtu.be/SbHCdf_c7ss

    int viralAdvertising(int n) {
    int ans = 0, shared = 5;
    for(int i = 1; i <= n; i++){
        ans += shared / 2;
        shared = (shared/2)*3;
    }
    return ans;
}

    public static int viralAdvertising(int n) {
        int totalLikes = 0;
        int shares = 5;
        
        for (int i = 1; i <= n; i++) {
            int likes = shares / 2;
            totalLikes += likes;
            
            shares = likes * 3;
        }

        return totalLikes;
    }

    def viralAdvertising(n):
    shared=5
    liked=shared//2
    cumu=liked
    if n<2:
        return cumu
    while n>1:
        shared=liked*3
        liked=shared//2
        cumu+=liked
        n-=1
    return cumu

    RUST:

    fn viralAdvertising(n: i32) -> i32 {
    let mut cumulation: i32 = 0;
    let mut p: i32 = 5;
    
    for _ in 1..=n {
        cumulation += p/2;
        p = p/2 *3;
    }
    cumulation
}

    easy approach 

    public static int viralAdvertising(int n) {
    if (n <= 0) return -1;
    int likes = 0;
    int peopleShare = 5; 
    for (int i = 1; i <= n; i++) {
        int peopleLike = (int) Math.floor(peopleShare / 2); // 2
        likes += peopleLike;
        peopleShare = peopleLike * 3;
    }
    return likes;
}
