1. Palindrome
2. Remove duplicate characters
3. Largest string

Palindrome

Find whether a character array is palindrome or not

View the code

#include<bits/stdc++.h>
using namespace std;

bool palindrome(char a[], int l){
int i=0,j=l-1;
while(i<j){
if(a[i]!=a[j]) return false;
i++;j--;
}
return true;
}
int main(){
    char a[100];
    cin>>a;
    int l=strlen(a);
cout<< palindrome(a,l)<<endl;
}

Remove duplicate characters

Remove the consecutive duplicates characters from the character array

View the code

#include<bits/stdc++.h>
using namespace std;

void duplicate(char a[], int l){
int i=0;
if (l==1 || l == 0){
    return;
}
for(int j=1;j<l;j++){
    if(a[i] != a[j]){
    a[++i]=a[j];
    }
}
a[i+1]='\0';
}
int main(){
    char a[100];
    cin>>a;
    int l=strlen(a);
    duplicate(a,l);
    cout<<a;
}

Largest String

Find the largest string among million strings

View the code

#include<bits/stdc++.h>
using namespace std;

int main(){
    char a[100];
    char b[100];
    int n,maxlen=0;
    cin>>n;
    cin.get();
    while(n--){
    cin.getline(a,100);
    int l = strlen(a);
    if(l>maxlen){
    maxlen=l;
    strcpy(b,a);
    }
    }
    cout<<"string is: "<<b<<" length: "<<maxlen<<endl;
}
