Write a program that accepts the line of the text on the input and displays the number of entries of each word. When calculating, you should ignore the register of symbols (believe that the "word" and "word" are one and the same) and any punctuation marks.
Input format
One line containing arbitrary text.
Output format
Bring each unique word and through the colon with a gap its amount in the text. Each pair "Word: quantity" should be displayed on a new line. The order of the output of words does not matter.
Example
Input
HELLO, World! HELLO EVERYONE.
Output
HELLO: 2
world: 1
EVERYONE: 1
Hint
There will be no clue here, decide for yourself!
