Given alphanumeric string str, the task is to check if the count of Alphabets and count of Numbers are equal or not.
Examples:
Input: str = “GeeKs01234”
Output: Yes
Explanation:
The count of alphabets and numbers are equal to 5.Input: str = “Gfg01234”
Output: No
Explanation:
The count of alphabets are 3 whereas the count of numbers are 5.
Approach: The idea is to use the ASCII values of the characters to distinguish between a number and an alphabet. After distinguishing the characters, two counters are maintained to count the number of alphabets and numbers respectively. Finally, both the counters are checked for equality.
The ASCII ranges of the characters are as follows:
- Lowercase characters: 97 to 122
- Uppercase characters: 65 to 90
- Digits: 48 to 57
Below is the implementation of the above approach:
C++
// C++ program to check if the count of // alphabets and numbers in a string // are equal or not. #include <iostream> using namespace std; // Function to count the // number of alphabets int countOfLetters(string str) { // Counter to store the number // of alphabets in the string int letter = 0; // Every character in the string // is iterated for (int i = 0; i < str.length(); i++) { // To check if the character is // an alphabet or not if ((str[i] >= 'A' && str[i] <= 'Z') || (str[i] >= 'a' && str[i] <= 'z')) letter++; } return letter; } // Function to count the number of numbers int countOfNumbers(string str) { // Counter to store the number // of alphabets in the string int number = 0; // Every character in the string is iterated for (int i = 0; i < str.length(); i++) { // To check if the character is // a digit or not if (str[i] >= '0' && str[i] <= '9') number++; } return number; } // Function to check if the // count of alphabets is equal to // the count of numbers or not void check(string str) { if (countOfLetters(str) == countOfNumbers(str)) cout << "Yes\n"; else cout << "No\n"; } // Driver code int main() { string str = "GeeKs01324"; check(str); return 0; } |
