• The input file will have multiple proposed tokens on each line. There also might be lines with no proposed tokens and / or just or extra whitespace.

• The proposed tokens will be separated by whitespace, which is to be ignored.

• Your program will consider successive tokens from the input file and classify them as 'FP', 'STR', 'INT', or 'does not match'.

• An FP is one or more decimal digits, followed by a right parenthesis, followed by a left parenthesis, followed by one or more decimal digits.

• A STR is a vertical bar (|) followed by zero or more uppercase letters and decimal digits followed by a plus sign (+).

• An INT is a octothorpe sign (#) followed by one or more decimal digits or letters R through W. The letters may be uppercase or lowercase. (That is, r through w are allowed.)

  Examples:

000)(000 is a legal FP. 1)(1 is a legal FP. )000 is not a legal FP. 000( is not a legal FP. 1.1 is not a legal FP.

|+ is a legal STR. |1+ is a legal STR. |HITHERE+ is a legal STR. |a+ is not a legal STR. "abc" is not a legal STR. A+ is not a legal STR. |A is not a legal STR.

#rSt is a legal INT. #0 is a legal INT. #r0 is a legal INT. #W is a legal INT. 123 is not a legal INT. rSt is not a legel INT.
