Write a Java program that includes predicates (functions which return a logical value) to find special integers called K-numbers. A positive integer X is a K-number if:
1. X is an odd integer, and
2. X is a square (X = N*N), and
3. X is symmetric (if the digits are reversed, the number is unchanged). A symmetric integer is called a palindrome.
Your program should include the following predicates:
a. boolean OddInt(long X): return value is true if X is an odd integer, and false otherwise.
b. boolean SquareInt(long X): return value is true if X is a perfect square, and false otherwise.
c. boolean SymmetricInt(long X): return value is true if X is symmetric, and false otherwise.
d. boolean KNumber(long X): return value is true if X is a K-number, and false otherwise. This function should be defined using the above three functions in the following logical rule:
KNumber(X) if OddInt(X) and SquareInt(X) and SymmetricInt(X)
In a Java program, the boolean datatype with values true and false can be used to represent logical variables.
Have your program receive two integer values N1 and N2 as command-line input. Then check all integers from N1 to N2 to find and display any K-numbers within that range.
Run your program for the following input ranges:
1. N1 = 1 N2 = 1,000
2. N1 = 1,000 N2 = 1,000,000
3. N1 = 1,000,000 N2 = 10,000,000
Can you find any larger K-Numbers?
