C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int a;
	cin>>a;
	if(a==1){
		cout<<"  *"<<endl;
		cout<<" ***"<<endl;
		cout<<"*****"<<endl;
	}
	if(a==2){
		cout<<"***"<<endl;
		cout<<"***"<<endl;
		cout<<"***"<<endl;
	}
	if(a==3){
		cout<<"  *"<<endl;
		cout<<" ***"<<endl;
		cout<<"*****"<<endl;
		cout<<" ***"<<endl;
		cout<<"  *"<<endl;
	}
	return 0;
}

Python :

# coding=utf-8
n=int(input())
if (n==1):
    print("  *")
    print(" ***")
    print("*****")
if (n==2):
    print("***")
    print("***")
    print("***")
if (n==3):
    print("  *")
    print(" ***")
    print("*****")
    print(" ***")
    print("  *")
