C :

#include<stdio.h> 


int main(){ 
	int n,i,j,z;
	scanf("%d",&n);
	//负责行 
	for(i = 1;i <= n;i++){
		//负责空格
		for(j = 1;j <= n - i;j++){
			printf(" "); 
		} 
		//负责打印数字
		for(z=1;z <= 2 * i - 1;z++){
			printf("%d",z); 
		} 
		
		//负责换行
		printf("\n"); 
		
	}

	return 0; 
} 

C++ :

#include<iostream>
#include<cmath>
using namespace std;
int main() {             
   char c;
   int i,t,n,j;
   cin>>n;
   for(i = 1;i <= n;i++){
      for(j = 1;j <=n - i;j++){
         cout<<' ';   	  	
	  }
   	  for(j = 1;j <=2 * i - 1;j++){
         cout<<j;   	  	
	  }
	  cout<<endl;
   }
}

Python :

n = int(input())
for i in range(1, n + 1):
    for j in range(1, n - i + 1):
        print(' ', end='')
    for j in range(1, 2 * i - 1 + 1):
        print(j, end='')
    print()
