[@mohanraja1350]

you explained the method by using splice wonderfully, its really pleasure to learn with you thank you

[@Ajishshandilya]

for the first approach in leetcode it is showing the error of TLE(Time Limit Exceed)
and for 2nd it will fail in the below scenario.
take these inputs
let arr = [1,2];
let k = 5;
expected O/p is [2,1]
actual O/P is [1,2]

[@mdashifal117]

use k = k % arr.length

[@anujadi8366]

Very well explained

[@bosin4035]

Thank u Jtech

Hi, when I use the 2nd solution with splice, the test case arr = [1,2] arrayRotation = 1, it fails and I am not sure why.

[@codingismyreligion]

It's because when you see and k is longer than nums you will get a negative value and be trying to delete values at an index that doesn't exist.
This video is from May 2021 and Leet Code must have updated the problem with some new test cases.

[@vinothkumarn4780]

A very good explanation. Thanks buddy!

[@RethinkingUI]

Thank u

[@vinothkumarn4780]

@@RethinkingUI could you please explain rotate array not using pop and other methods. Instead, only using while loop and for loops. And saving in temp variable.

[@vinothkumarn4780]

@@RethinkingUI I mean, help me understand the following code.
let arr=[1,2,3,4,5,6,7];
let k=3;
let count=0;
let val=arr[0];
let rep=0;
let i=0;
while(count

[@pratikshaandsaurabhwedding7466]

Very well explained brother

[@RethinkingUI]

Thank you

[@theone-pq9tp]

Thanks bhai

[@irkfaisal]

Can you tell me the methods for rotating it in left direction (to last position of an array).

[@RethinkingUI]

Try Array shift method

[@irkfaisal]

@@RethinkingUI yes it worked array.push(array.shift());
Thanks i understand this rotation array logics. Very simple

[@mrnabby4178]

sahi dimaag lagaya bhai.

[@RethinkingUI]

Thank you

[@anurag5362]

thank u bro but how to solve without inbuilt function ?

[@irkfaisal]

Why the console final output is underfined.

[@RethinkingUI]

final output console is the console which we are calling the function. As that function not returning anything. We got the final console output as undefined. In fact we no need to put the function call in the console log.

[@irkfaisal]

@@RethinkingUI yes after i return the function i got solved

[@mahendrapaswan3496]

Nice concept
