C++ Exercises: Create a new string from a given string. If the first or first two characters is 'a', return the string without those 'a' characters otherwise return the original given string

C++ Basic Algorithm: Exercise-80 with Solution

Write a C++ program to create a new string from a given string. If the first or first two characters is 'a', return the string without those 'a' characters otherwise return the original given string.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string test(string s1)
          {
            if (s1.length() == 1 && s1.substr(0, 1) == "a")
            {
                s1 = s1.erase(0, 1);
            }

            if (s1.length() > 1)
            {
                if (s1.substr(1, 1) == "a")
                {
                    s1 = s1.erase(1, 1);
                }

                if (s1.substr(0, 1) == "a")
                {
                    s1 = s1.erase(0, 1);
                }
            }

            return s1;
        }         
        
int main() 
 {
  cout << test("abcab") << endl;  
  cout << test("python") << endl; 
  cout << test("aacda") << endl;  
  cout << test("jython") << endl;  
  return 0;    
}

Sample Output:

bcab
python
cda
jython

Previous: Write a C++ program to create a new string from a given string without the first and last character if the first or last characters are 'a' otherwise return the original given string.
Next: Write a C++ program to check a given array of integers of length 1 or more and return true if 10 appears as either first or last element in the given array.
