A simple server-client calculator in Golang!
How it works:
client sents a string of serveral numbers with + or - characters and without any white spaces in the middle.
For example: 3+234-232+2676-44
(UPDATE: can take several space sepated strings and calculate each of them
Example: 23+5 345-1+3
Result:28
Result:347 )
Then, server sends back the result of the calculation.
