check if 2 arrays are equal code example

Example 1: check if 2 arrays are equal javascript

const a = [1, 2, 3];
const b = [4, 5, 6];
const c = [1, 2, 3];

function arrayEquals(a, b) {
  return Array.isArray(a) &&
    Array.isArray(b) &&
    a.length === b.length &&
    a.every((val, index) => val === b[index]);
}

arrayEquals(a, b); // false
arrayEquals(a, c); // true

Example 2: check if 2 arrays are equal javascript

var arraysMatch = function (arr1, arr2) {

	// Check if the arrays are the same length
	if (arr1.length !== arr2.length) return false;

	// Check if all items exist and are in the same order
	for (var i = 0; i < arr1.length; i++) {
		if (arr1[i] !== arr2[i]) return false;
	}

	// Otherwise, return true
	return true;

};

Example 3: example to check two integer array are equal in java?

import java.util.Arrays;

public class JavaArrayConceptsConitnue
{
	public static void main(String[] args)
	{
		int[] x = {10,12,20,30,25};
		int[] subx = new int[]{10,12,20,30,26};
		
		if(Arrays.equals(x, subx) == true)
		{
			System.out.println("Both the arrays are equal");
		}
		else
		{
			System.out.println("Arrays are not equal");
		}
	}
}

Example 4: equal elements in two arrays in c++

bool equalelementsintwoarrays(int A[], int B[], int N) {
    sort(A, A+N);
    sort(B, B+N);
    int i = 0, j = 0;
    while (i < N && j < N) {
        if (A[i] == B[j]) return true;
        else if (A[i] > B[j]) j++;
        else i++;
    }
    return false;
}
