Even or Odd

Checking Number is Even Or Odd Is very Easy Task .

1. num=int(raw_input())
2. if num%2==0:
3.     print 'Even'
4. else:
5.     print 'Odd'

But If Someone say I gave you lots of Numbers to check Until I satisfied that your Program is correct .
And number is in range 0 to 10^10000



Than what will you do .

First Problem is , We don't Know number of Input user want to give 

     

•  We Need TO create A infinite LOOP , with a condition To break .

Second Problem is , Taking integer data of order 10^10000

• We can't store data as int or float . Even if we can it is meaningless because checking Even or ODD using division is wastage of time . So store data as string

Third Problem is , How to check in optimize time

• We know Property of  Even Numbers if Number ends with {0,2,4,6,8} then even else Odd . So Just check last character of each string .

Python Code to Check Even or ODD :

1. hile True: #infinite LOOP
2.     inp=raw_input() # Taking Input As String
3.     if inp=='-1': #Condition To break Out From LOOP
4.         break
5.     if inp[-1] in '02468': #cheking Last digit of input to check Even or ODD
6.         print 'EVEN'
7.     else:
8.         print 'ODD'
