The harbor control tower at Meridian Port broadcasts departure announcements to ships over an aging relay line. The relay hardware has one quirk that everyone on the docks has learned to expect: it always retransmits the words of a message in reverse order, while leaving the letters inside each word completely untouched, and it always separates the retransmitted words with exactly one space and no leading or trailing space. You are given the original announcement exactly as the harbor operator typed it. Simulate what the relay line broadcasts to the ships.

Input format

A single line containing the announcement s.

• s is non-empty, contains no leading or trailing spaces, and consists of one or more words separated by exactly one space.
• Each word is made of one or more visible (non-space) ASCII characters.

Output format

Print the relayed announcement on a single line: the same words, in reverse order, joined by exactly one space each, with no leading or trailing space.

Constraints

• 1 <= length of s <= 100000
• s consists of printable ASCII characters (codes 33-126) and the space character only
• No leading or trailing spaces; words are separated by exactly one space
