A Smith number is a composite number, the sum of whose digits is the sum of the digits of its prime factors obtained as a result of prime factorization (excluding 1). 124; by SMC ACADEMY. Write a program to input a number and display whether the number is a Smith number or not. In number theory, a Keith number or repfigit number (short for repetitive Fibonacci-like digit) is a natural number in a given number base with digits such that when a sequence is created such that the first terms are the digits of and each subsequent term is the sum of the previous terms, is part of the sequence. By definition, N is a Keith number if N appears in the sequence thus constructed. The sequence goes like this: 1, 9, 7, 17, 33, 57, 107, 197, 361, ... import java.io. Examples: Input : n = 4 Output : Yes Prime factorization = 2, 2 and 2 + 2 = 4 Therefore, 4 is a smith number Input : n = 6 Output : No Prime factorization = 2, 3 and 2 + 3 is not 6. Explanation of the above java buzz number program : The commented numbers in the above program denote the step numbers below : Define one integer variable no to store the user input value and one Scanner variable sc to read all user inputs. Keith Number //Write a program to accept a number and check it is a Keith number or not. Then continue the sequence, where each subsequent term is the sum of the previous n terms. This is very helpful.for my course. Units of Measurement CGS FPS MKS SI. If a Fibonacci sequence (in which each term in the sequence is the sum of the previous t terms) is formed, with is the first ‘t’ terms being the decimal digits of the number n, then n … In this program, we need to determine whether a given number is a happy number or not. August 16, 2015 at 1:59 pm. If N = 187, then n=3, the first three numbers of the sequence are 1, 8, 7 and n=3. If you seed it with the three digit number 197, then 197 will (possibly coincidentally) be seen as a Keith number. Keith numbers were introduced by Mike Keith in 1987. ; In this step, we are creating three strings. Blue Java Program For Keith Number. Reply. It is full of simple and easy programmes.
