Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.*;
import java.io.*;
public class Exercise107 {
public static void main(String[] args)
{
int[] array_nums = {11, 12, 13, 14, 45, 20};
System.out.println("Original Array: "+Arrays.toString(array_nums));
int result =1;
for(int i = 0; i <= array_nums.length - 3; i++) {
if(array_nums[i] + 1 == array_nums[i+1] && array_nums[i+1] + 1 == array_nums[i+2])
result =0;
}
if (result==1)
{
System.out.printf(String.valueOf(false));
}
else
{
System.out.printf(String.valueOf(true));
}
System.out.printf("\n");
}
}
