#### "Count the number of occurrences of a character in a string"

This technical problem involves writing a function that takes a string and a character as arguments, and returns the number of times the character appears in the string.

#### Problem

```Your task is to write a function that takes two arguments, a string and a character, and returns the number of times the character appears in the string.
Example input: "hello world", "o"
Example output: 2```

#### Solution

This solution is in SQL. Our A.I. can create solutions in multiple languages.
```SELECT LENGTH(string) - LENGTH(REPLACE(string, character, '')) AS count
FROM table
WHERE string = 'hello world' AND character = 'o';

/*

The above solution is optimal because it uses the built-in LENGTH and REPLACE functions to find the number of times the character appears in the string.

*/```

A.I. Evaluation of the Solution
