Telegraph Dispatch Word Quota

In the era of pay-by-the-word telegraphy, a dispatcher wants to preview a long outgoing message by keeping only its first several words, since every additional word raises the cost of the wire. A dispatch is given as a single line of words separated by exactly one space each, with no leading or trailing spaces; every word is made up only of English letters (upper- and lower-case). Given the dispatch and an integer k, produce the dispatch truncated to just its first k words, in their original order, still separated by single spaces.

Input format

• Line 1: the dispatch, a string of words separated by single spaces (no leading/trailing spaces).
• Line 2: an integer k.

Output format

A single line containing the first k words of the dispatch, joined by single spaces, with no leading or trailing space.

Constraints

• 1 <= number of words in the dispatch <= 100
• 1 <= length of each word <= 20
• 1 <= k <= number of words in the dispatch
• Every word consists only of uppercase and lowercase English letters (no digits, punctuation, or extra whitespace).
