Given that A,B,C,D,E each represent one of the digits between 1 and 9 and that the following
multiplication holds:
A B C D E
X 4
E
D C B A
what
digit does E represent ?

• 8, because A should be either 1 or 2. and 4A=E, 4E=A
  and then A = 2, and E = 8

• Qis A B C D E
  X 4
  EDCBA
  than we take max value of a is 1 or 2 so if we take a=2 than value of E=8 so it satisfy this condition so E=8

• 1.die is used to throw an exception(catchable using eval) and exit is used to exit the process.
  2.die will set the error code based on $! or $? if the exception is uncaught andexit will set the error code based on its argument.
