Conversion into CamelCase
Your mission is to convert the name of a function from the Python format (for example "my_function_name") into CamelCase ("MyFunctionName") where the first char of every word is in uppercase and all words are concatenated without any intervening characters.
Input: A function name as a string (string).
Output: The same string (string), but in CamelCase.
Examples:
assert.strictEqual(toCamelCase("my_function_name"), "MyFunctionName");
assert.strictEqual(toCamelCase("i_phone"), "IPhone");
How it is used: To apply function names in the style in which they are adopted in a specific language (Python, JavaScript, etc.).
Precondition:
0 < len(string) <= 100
Input data won't contain any numbers.
