C++ Exercises: Check if the first appearance of 'a' in a given string is immediately followed by another 'a'
C++ Basic Algorithm: Exercise-27 with Solution
Write a C++ program to check if the first appearance of "a" in a given string is immediately followed by another "a".
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
bool test(string str)
{
int counter = 0;
for (int i = 0; i < str.length()-1; i++)
{
if (str[i] == 'a') counter++;
if(str.substr(i, 2) == "aa" && counter < 2)
return true;
}
return false;
}
int main()
{
cout << test("caabb") << endl;
cout << test("babaaba") << endl;
cout << test("aaaaa") << endl;
return 0;
}
Sample Output:
1 0 1
