Following code is the solution for

1 22 111 2222 11111

Code in "C Programming Language"

#include <stdio.h>

int main()
{
    int i,j, m=1, n=2;
    
    for(i=1; i<=5; i++)
    {
        for(j=1; j<=i; j++)
        {
            if(i%2 == 1)
                printf("%d", m);
            else
                printf("%d", n);
        }
        printf(" "); /* \n is replaced with space */
    }
    
    return 0;
}

Code in "Python Programming Language"

for i in range(1, 6):
    for j in range(1, i+1):
        if(i%2 == 1):
            print(1, end="")
        else:
            print(2, end="")
    print("", end=" ")

I assume that you are asking for the following output

1

22

111

2222

11111

If yes, then following code is the solution

written in "C Programming Language" :

#include <stdio.h>

int main()
{
    int i,j, m=1, n=2;
    
    for(i=1; i<=5; i++)
    {
        for(j=1; j<=i; j++)
        {
            if(i%2 == 1)
                printf("%d", m);
            else
                printf("%d", n);
        }
        printf("\n");
    }
    
    return 0;
}

Written in "Python Programming Language" :

for i in range(1, 6):
    for j in range(1, i+1):
        if(i%2 == 1):
            print(1, end="")
        else:
            print(2, end="")
    print("\r")

Hope this helps..

public static void main(String[] args) {
  
  int even = 2;
  int odd = 1;
  
  for(int i=1;i<=20; i++){
      if(i%2 == 0){

for i in range(5):
    if(i % 2 == 0):
        num = "1"
    else:
        num = "2"
    string = num
    for b in range (i):
        string += num
    print(string)

count = 1
for i in range(1,6):
    if((i%2) == 0):
        print('2'*count)
    else:
        print('1'*count)
    count = count + 1
