Parenthesis Pattern

The program must accept a string $ as the input. The program must print the desired pattern as shown in the Example Input/Output section.

Boundary Condition(s):
1 < Length of S <= 1000

Input Format:
The first line contains S.

Output Format:
The lines containing the desired pattern as shown in the Example Input/Output section.

Example Input/Output 1:
Input:
SkillRack
Output:
(S)killRac(k)
S(k)illRa(c)k
Sk(i)llR(a)ck
Ski(l)l(R)ack
Skil(l)Rack

Example Input/Output 2:
Input:
hide
Output:
(h)id(e)
h(i)(d)e

#include<stdio.h>
#include<stdlib.h>

int main()
{
	char a[1000]; 
	scanf("%s",a); 
	int x=0,y-strlen(a)-1;
	while(x<=y)
	{
		for(int i=0;i<strlen(a);i++)
		{
			if(i==x||i==y) 
				printf("(%c)",a[i]); 
			else 
				printf("%c",a[i]);
		} 
		printf("\n");
		x++;
		y--;
	}
