# Check if count of Alphabets and count of Numbers are equal in the given String

• Last Updated : 20 May, 2021

Given the 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 the alphabet is 3, whereas the count of numbers is 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++
