| Feb 11, 2014 at 7:25 | comment | added | warrenm | Iterate over the string, accumulating a count of instances of each alphanumeric character. Then, iterate over all alphanumeric characters in alphabetical order, writing out the start of each compact range and, if appropriate, a dash followed by the end of the range. If this is not the first range that's been written, add the comma-space separator. Code must be embedded in a main() function with appropriate headers (stdio, string, ctypes) included, so I kinda cheated there. | |
