# One Dimension Array

#### Example Programs

**Program [1]**

Write a Program in Java to input a number and check whether it is a **Keith Number** or not.

Note: A Keith Number is an integer N with ‘d’ digits with the following property:

If a Fibonacci-like sequence (in which each term in the sequence is the sum of the ‘d’ previous terms) is formed, with the first ‘d’ terms being the decimal digits of the number N, then N itself occurs as a term in the sequence.

For example, 197 is a Keith number since it generates the sequence 1, 9, 7, 17, 33, 57, 107, 197, ………..

Some keith numbers are: 14 ,19, 28 , 47 , 61, 75, 197, 742, 1104, 1537……………

**Sample**

Enter the number : 197

The number is a Keith Number

Enter the number : 14

The number is a Keith Number

Enter the number : 53

The number is a not a Keith Number

**Program [2]**

Write a program to input a natural number less than 1000 and display it in words.

Test your program for the given sample data and some random data.

INPUT: 29

OUTPUT: TWENTY NINE INPUT: 17001

OUTPUT: OUT OF RANGE INPUT: 119

OUTPUT: ONE HUNDRED AND NINETEEN INPUT: 500

OUTPUT: FIVE HUNDRED
