The program must accept a string S and an integer K as the input. The program must reverse the middle K characters in S. Then the program must print the modified string as the output.
Note: The length of S and the integer K are always either odd or even.
Boundary Condition(s):
1 <= Length of S <= 100
1 <= K <= Length of S
Input Format:
The first line contains the string S.
The second line contains the integer K.
Output Format:
The first line contains the modified string.
Example
Input:
acknowledgement
7
Output:
acknegdelwoment
Program
#include<stdio.h>
#include <stdlib.h>
#include<string.h>
int main()
{
int K,cnt=0,i=0,j,a,l;
char S[100],tmp[100];
scanf("%s%d",S,&K);
a=strlen(S);
if ((a%2==0 && K%2==0) || (a%2!=0 && K%2!=0))
{
cnt=K;
j=(a-K)/2;
l=j;
while (cnt>0)
{
tmp[i++]=S[l++];
cnt--;
}
tmp[i]='\0';
for(l=j,i=i-1;i>=0;--i)
S[l++]=tmp[i];
printf("%s",S);
}
}
