Solution :

Code in C :

#include <stdio.h>


int main() {
    int n, i,j;
    scanf("%d", &n);
    for(i=0;i<n;i++)
        {
        for(j=0;j<n;j++)
            {
            if(j<(n-1-i)) printf(" ");
            else printf("#");
            }
        printf("\n");
    }
  
    return 0;
}

Code in C++ :

#include <iostream>
using namespace std;


int main() {
    
    int n,i,j,k;
    cin>>n;
    for(i=1;i<=n;i++)
    {
        for(j=1;j<=n-i;j++)
        {
            cout<<" ";    
        }
        for(k=j;k<=n;k++)
        {
            cout<<"#";    
        }
        cout<<"\n";
    }
     
    return 0;
}



Code in python :
def plusminus(n): k=map(int,input().split()) p=0 ne=0 z=0 for i in k: if i>0: p+=1 elif i==0: z+=1 elif i<0: ne+=1 print (round((p/n),3)) print (round((ne/n),3)) print (round((z/n),3)) n=int(input()) plusminus(n)
