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. Oftentimes while operating upon Strings, we need to figure out whether a Stringis a valid number or not. An n-digit number with value N is a Keith number if N is part of the Keith series generated. If the number N appears in the series, it is called a Keith number. By applying this rule, following are numbers in the sequence. A Smith Number is a composite number whose sum of digits is equal to the sum of digits in its prime factorization. if a fibonacci like sequence Then continue the sequence, where each subsequent term is the sum of the previous n terms. 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. The abstract class Number is the superclass of classes BigDecimal, BigInteger, Byte, Double, Float, Integer, Long, and Short..
