Find The Missing Number of Array

We are going to use javascript to find out missing number of array

Before going to start please make sure you have some basic knowledge of javascript. If you don’t have basic understanding of javascript it doesn’t make a seance to go through this article because you didn’t get it what does exactly happen . I will create some simple steps which you need to follow. If you follow these steps at the end of these article i am damn sure you will get understand. How things are going to work that’s it so Let’s get started to our journey.

We can do it using different ways. Now in this article i wanna use two different methods I will get more clarity.

Method 1:

STEP 1:

Create a new function. I am going to use ES6 arrow function. It’s not necessary to use arrow function you can use any both of them so here i will used arrow function because i personally like it. creating a function like FindMissingElement and create new array.

STEP 2:

Create new variable inside function It will help you to store increment of you count

STEP 3:

Create Loop over array because each and every index value

STEP 4:

Use for loop for comparing to the element of array

STEP 5:

Final our code look like this

That’s it. You will get final ans and of course it will return our missing element

Let’s start to do it in a different way

METHOD 2

STEP 1:

Declare variable and assigning value

Here count in the seance range of our array

create new empty array to store our missing value

Empty array

STEP 2:

Insert for loop to access each and every element of array

For Loop

STEP 3:

here we are checking missing element with the help of if condition and pushing it into our empty array

STEP 4:

Finally our entire code look like this

That’s it you will get the final missing element of array.
