## Description

A pair of English letters (a, b) is considered beautiful iff one of them is uppercase, the other is lowercase and both of them are consonants. (English letters except a, e, i, o, u, w and y). Now give you a string which is consists of lowercase English letters. Now you can change several letters from lowercase to uppercase. Please write a program to calculate the maximum number of beautiful pairs formed by adjacent letters.

Note: If you change x to X, then all x in the string will become X.

For example, if we have string strength, we can change it to StRenGtH. In this case, (S,t), (t,R),(n,G),(G,t) and (t,H) are beautiful. So the result is 5.

## Input

## Output

## Sample Input

2
