Java Basic Exercises: Check if an array of integers contains three increasing adjacent numbers

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");
 }
}

Sample Output:

Original Array: [11, 12, 13, 14, 45, 20]                               
true
