Level: Easy1 of 10
Topics: String, Implementation
Solved: No attempts yet

Problem

The pronunciations of 2 and e are similar, so mixing the two when speaking can annoy the listener.

Jimin is using this to drive Eunsu crazy. Given the string s that Jimin said to Eunsu, help determine whether 2 appears more often or e appears more often.

Input

The first line gives the length of the string s.

The second line gives the string s. The length of s is between 1 and 105 inclusive, and s consists only of 2 and e.

Output

If 2 appears more often, output 2; if e appears more often, output e. If the counts are equal, output "yee" (excluding the quotation marks).
