Given string stringValue on one line, string addStr on a second line, and string partialString on a third line, insert the contents of addStr in stringValue right before the first occurrence of partialString. Ex: If the input is: FuzzyBear Wuzzy Be then the output is: FuzzyWuzzyBear #include #include using namespace std; int main() {    string stringValue;    string addStr;    string partialString;    getline(cin, stringValue);    getline(cin, addStr);    getline(cin, partialString);    /* Your code goes here */        cout << stringValue << endl;        return 0; }

StringBuilder objects should be used in place of String objects if O is more than 80 characters long. the string may grow. O the string is declared final. O the tring needs to be initialized.

int main(){    string str;    int count = 0;    // user input    cout << "Enter string: ";    cin >> str;    int n = str.length();    // iterating over the string    for (int i = 0; i < n - 1; i++)    {        // calling the fucntion to find the palidrome strings from the user input        if (isPalindrome(0, i, str) && isPalindrome(i + 1, n - 1, str))        {            // if 2 substring are palindrome then print them and increment count            for (int x = 0; x < i + 1; x++)                cout << str[x];            cout << " ";            for (int x = i + 1; x < n; x++)                cout << str[x];            count++;            // break the loop after printing the palindrom string            break;        }    }    // if count is 0 then no palindrome subtring pair found    if (count == 0)        cout << "NO";} change this code to stdio.h string.h
