Task 1: "Valid Phone Numbers

You are given a text file.

Write a script to display all valid phone numbers in the given text file.
Acceptable Phone Number Formats

+nn  nnnnnnnnnn
(nn) nnnnnnnnnn
nnnn nnnnnnnnnn

Input File

0044 1148820341
 +44 1148820341
  44-11-4882-0341
(44) 1148820341
  00 1148820341

Output

0044 1148820341
 +44 1148820341
(44) 1148820341
"

My notes: as the valid formats are fixed, just a load of regexes.
Would have been more interesting if the formats were inputs too.


Task 2: "Transpose File

You are given a text file.

Write a script to transpose the contents of the given file.
Input File

name,age,sex
Mohammad,45,m
Joe,20,m
Julie,35,f
Cristina,10,f

Output:

name,Mohammad,Joe,Julie,Cristina
age,45,20,35,10
sex,m,m,f,f
"

My notes: simple to state.  Basically read into 2-D array and transpose
array.
