                                                     Pattern Printing - String Characters

Given a string S of length L, the program must print the pattern as described in the Example Input/Output.

Input Format:
First line contains the string S.

Output Format:
L lines containing the desired pattern.

Boundary Condition:
2 <= L <= 100

Example Input/Output 1:
Input:
ABCD

Ouput:
A
BB
CCC
DDDD

Example Input/Output 2:
Input:
EAGLE

Ouput:
E
AA
GGG
LLLL
EEEEE

C program:

#include<stdio.h>

#include <stdlib.h>

int main()

{

char a[100],ch;

int i=0;

while((ch=getchar())!='\n')

a[i++]=ch;

a[i]='\0';

i=0;

while(a[i]!='\0')

{

 for(int j=0;j<=i;j++)

 printf("%c",a[i]);

 i++;

 printf("\n");

}

}
