Note: this task is only for students of "Formal languages and
|
|
complexity theory" taught in English.
|
|
|
|
[Your program should read lines from the standard input and check each
|
|
line separately (without end-of-line character). Please use regular
|
|
expressions as much as possible (in particular, try not to use
|
|
logical operators outside the regeular expression). If it is
|
|
possible, use just one regular expression.]
|
|
|
|
For each string from the standard input, extract minutes from a string
|
|
representing an hour ("9:13", "18:44", etc.) and write it on the
|
|
standard output. If the input string is not an hour, write "<NONE>" on
|
|
the standard output.
