A coast-guard relay station receives short alert phrases from patrol boats and must compress each phrase into a single beacon code before it can be transmitted over a narrow-band radio channel. The station's encoding hardware follows a fixed procedure:

1. The phrase is split into words wherever a single space occurs.
2. The words are joined together with no spaces between them, rewriting the case of every letter as follows: the first word is written entirely in lowercase; every word after the first has its own first letter capitalized (uppercase) with all of its remaining letters written in lowercase. Call the resulting joined string the core.
3. If the core has fewer than 2 characters, the station aborts the transmission and the beacon code is the empty string.
4. Otherwise, the beacon code is formed by placing the character # in front of the core. If the beacon code (including the #) is longer than 100 characters, it is truncated by keeping only its first 100 characters.

Given one alert phrase, output the beacon code the relay station would transmit (which may be an empty line if the transmission is aborted).

Input format

A single line containing the phrase: one or more words made only of lowercase English letters, separated by exactly one space, with no leading or trailing spaces.

Output format

Print a single line: the beacon code (this line may be empty if the core has fewer than 2 characters).

Constraints

• 1 <= length of the phrase <= 200
• 1 <= number of words <= 100
• Every word consists of at least 1 lowercase English letter.
• Words are separated by exactly one space; there are no leading or trailing spaces.
