  1. Write a function to convert the input string from hexidecimal numbers to binary numbers.

     Write a main program to test it. The program will iterately read a hexidecimal number and print out its binary equivalent, like

     0x45
     	= 01000101  
     

     The program stops at any empty input.
  2. Write a program which scans an input string and print the parenthesis count below the corresponding character, like

     ( 2 + (3-1) * (5 - 2))
     1     2   1   2     10
