Question

How to find two numbers from an array that are just smaller and just greater than N in Java

Answer 1

public class MyClass {
    public static void main(String args[]) {
        int[] arr = {3, 8, 1, 9, 4, 10, 7, 13, 2, 6};
	    int size = arr.length;
	    int N = 4;

	    int just_greater = Integer.MAX_VALUE;
	    int just_smaller = Integer.MIN_VALUE;

	    for (int i = 0; i < size; i++) {
		    if (arr[i] > N && arr[i] < just_greater) {
			    just_greater = arr[i];
		    }

		    if (arr[i] < N && just_smaller < arr[i]) {
			    just_smaller = arr[i];
		    }
	    }

	    System.out.println("just_smaller: " + just_smaller);
	    System.out.println("N: " + N);
	    System.out.println("just_greater: " + just_greater);
    }
}



/*
run:
 
just_smaller: 3
N: 4
just_greater: 6
 
*/
