Given a string with text and digits, add all the numbers together.
Examples:
Input str = '4 and 20 blackbirds baked in a pie' Output total is 24
Input str = '2 4 6 8 who do we appreciate?' Output total is 20
Very nice !
This problem shouldn't be named "Summing digits...." because it is the wrong approach. In the first example you sum numbers because 20 is not a digit. If it was - then it should be sum = 6.
What if there are decimals "I have $3.25 in 4 pockets" ? Should the answer be 7.25 or 32?
this is hard
I'm cheating a bit here (by parsing out the dash and dollar sign)
That's cheating.
