How to create a Coordinates Validator in Golang
The challenge
You need to create a function that will validate if given parameters are valid geographical coordinates.
Valid coordinates look like the following: “23.32353342, -32.543534534”. The return value should be either true or false.
Latitude (which is the first float) can be between 0 and 90, positive or negative. Longitude (which is the second float) can be between 0 and 180, positive or negative.
Coordinates can only contain digits, or one of the following symbols (including space after the comma)
There should be no space between the minus “-” sign and the digit after it.
Here are some valid coordinates:
- -23, 25
- 24.53525235, 23.45235
- 04, -23.234235
- 43.91343345, 143
- 4, -3
And some invalid ones:
- 23.234, – 23.4234
- 2342.43536, 34.324236
- N23.43345, E32.6457
- 99.234, 12.324
- 6.325624, 43.34345.345
- 0, 1,2
- 0.342q0832, 1.2324
