+# In Python, a string can be split on a delimiter.
+
+# Example:
+
+# >>> a = "this is a string"
+# >>> a = a.split(" ") # a is converted to a list of strings. 
+# >>> print a
+# ['this', 'is', 'a', 'string']
+# Joining a string is simple:
+
+# >>> a = "-".join(a)
+# >>> print a
+# this-is-a-string 
+# Task 
+# You are given a string. Split the string on a " " (space) delimiter and join using a - hyphen.
+
+# Input Format 
+# The first line contains a string consisting of space separated words.
+
+# Output Format 
+# Print the formatted string as explained above.
+
+# Sample Input
+
+# this is a string   
+# Sample Output
