Map the given integer to a month.

Example:

• For mo = 1, the output should be getMonthName(mo) = "Jan",
• For mo = 0, the output should be getMonthName(mo) = "invalid month".

Find the number of even digits in the given integer.

Example

• For n = 1010, the output should be numberOfEvenDigits(n) = 2.
• For n = 123, the output should be numberOfEvenDigits(n) = 1.

Given a string, return its encoding defined as follows:

First, the string is divided into the least possible number of disjoint substrings consisting of identical characters for example, "aabbbc" is divided into ["aa", "bbb", "c"] Next, each substring with length greater than one is replaced with a concatenation of its length and the repeating character for example, substring "bbb" is replaced by "3b" Finally, all the new strings are concatenated together in the same order and a new string is returned.
