http://technotip.com/6859/c-program-to-check-whether-a-number-is-strong-number-or-not/ Lets write a C program to check whether user entered number is strong number or not, using nested while loop. Strong Number: Sum of factorial of a number’s individual digits should be equal to the number itself. Such a number is called Strong Number. For Example: If user entered number is 145. We find factorial of individual digits of 145 and add it. i.e., !1 + !4 + !5 (1) + (24) + (120) = 145 So the original number and the sum of factorials of individual digits are both 145. So number 145 is considered as a Strong Number.

Input/Output: Enter 5 elements(0 or 1) 0 1 1 0 0 Array after segregating o’s to left and 1’s to right 0 0 0 1 1 In the program we also check if the user entered anything other than 0 or 1.
