How many Armstrong numbers are there between 1 and 1000?

An Armstrong number is an n-digit base b number such that the sum of its (base b) digits raised to the power n is the number itself. Hence 153 because 13 + 53 + 33 = 1 + 125 + 27 = 153. Here is source code of the C Program to print armstrong number from 1 to 1000.

Where is Armstrong number used?

Check Armstrong Number of n digits. Enter an integer: 1634 1634 is an Armstrong number. In this program, the number of digits of an integer is calculated first and stored in n . And, the pow() function is used to compute the power of individual digits in each iteration of the second for loop.

What is Krishnamurthy number?

A Krishnamurthy number is a number whose sum of the factorial of digits is equal to the number itself. Given a number N as input.

Why is 28 the perfect number?

A number is perfect if all of its factors, including 1 but excluding itself, perfectly add up to the number you began with. 6, for example, is perfect, because its factors — 3, 2, and 1 — all sum up to 6. 28 is perfect too: 14, 7, 4, 2, and 1 add up to 28.

How do you know if a number has the same number?

Given two integers A and B, the task is to check whether both the numbers have equal number of digits. Approach: While both the numbers are > 0, keep dividing both the numbers by 10. Finally, check if both the numbers are 0.

Which is the smallest Armstrong number?

Other than the numbers 1 through 9, it is the smallest Armstrong number; there are none with two digits. After 153, the next smallest Armstrong numbers are 370, 371, 407, 1,634, 8,208, and 9,474. There are only 89 Armstrong numbers in total.

What are strong numbers?

Strong number is a number whose sum of all digits’ factorial is equal to the number ‘n’. Factorial implies when we find the product of all the numbers below that number including that number and is denoted by ! (Exclamation sign), For example: 4! = 4x3x2x1 = 24.

What is Armstrong number in Java?
