Task

You are given a positive integer n, and your goal is to compute the count of odd digits in the number n.

Special Condition

You need to count how many digits in n are odd (1, 3, 5, 7, 9).

Constraints

• The input n will be a positive integer such that 5 ≤ n ≤ 9999999.
• The result should reflect the count of odd digits in the number n.
• Code golf restriction: maximum solution length of 37 characters.

Example

For instance:

• The count of odd digits in 234 is 1 (only the digit 3 is odd).

• For the number 405, the count of odd digits is 1 (only 5 is odd).

• For the number 111, the count of odd digits is 3 (all digits are odd).

• For the number 2468, the count of odd digits is 0 (all digits are even).

• You cannot use built-in functions (like str(), eval(), sum(), etc.)

• You also cannot import any external modules or libraries.

  
  Good luck!
