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 first float can be between 0 and 90, positive or negative. Longitude which is 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 comma , . There should be no space between the minus  sign and the digit after it. Here are some valid coordinates: 23, 25 43.91343345, 143 4, 3 And some invalid ones: 23.234,  23.4234 N23.43345, E32.6457 6.325624, 43.34345.345 0, 1,2 I'll be adding my attempt as well as my friend's solution took us  1 hour my attempt friends solutions using regular expression
