ROTATION of an array (REVERSAL Algorithm)

Reversal Algorithm for ROTATION of an array. Rotate the array by given places. You have to rearrange the array by displacing or pushing the elements by k places left or right as given.

[@totsubo2000]

Do you also have a video explaining how rotate an array using the Juggling Algorithm. It is more efficient than the reversal algorithm.

[@sandeepmunavalli6345]

Hello Sir, your videos are very good, I see and each and every video. please keep on adding videos. I am learning lot

[@karthikk5895]

You gotta use r %= n to make sure the indices are bounded.

[@ricardoorellana1168]

Hello Sir, what books did you use to learn this rotation algorithms?

[@prajakta_patil]

Thank you so much :) Explanation is very clear and to the point. Appreciate your effort

[@tapanjeetroy8266]

Thanks for uploading it.. You are doing a great job.. Please upload more videos of competitive programming.. We really need it

[@thesoftwareengineer17]

Hey Vivek, dude u have some excellent teaching skills. thank you so much for such simple and understandable explanation.

[@Sanjeev.Network]

Awesome bro,Awesome You are doing great work. Keep helping us we keep sharing your channel.

[@ankitvarmait]

Thanks so much for such wonderful and simple explanation Required videos for Time complexity and Space complexity calculation in simple way

[@sushma6314]

Anything in place like this for left rotation ?

[@beaglesnlove580]

This guy is the best teacher

[@ruchu30]

you are awesome ... you made things simple :) . thanks a lot ...

[@rohitsancheti96]

hey man your videos are really helpful and to the point... cant thank you enough!!

[@coderix1404]

Thankyou so much. It was very clear & helpful.

[@SushrutKanetkar]

Thanks for the video !

[@mohitsaini9148]

yo man. you killed it...

[@ashwiniv7053]

Awesome explanation, I have a question, can we skip step two and add value B and value A

[@shivamnerwal72]

sir , you are doing a gret work

[@kishorjha5028]

thank u for this video its clear my concept

[@udayptp]

Simply awesome approach sir

[@satyanarayanakante7192]

Please explain about k-way merge algorithm

[@priyankashendage4823]

Thank you so much sir for this video..it helped me.!!

[@manojaswani7100]

Helpful indeed!

[@hariprasadg123]

Good explanation. But are you checking array bounds are not exceeded? Please clarify.

[@bhaskarnaik5842]

So good explanation sir thanks

[@jagdishwarbiradar1763]

hey buddy , can you tell where we can use this algorithm plzz.., otherwise nice explanation

[@VersaKumari-vu4ly]

easy to understand thanks sir😊

[@salihkurtov526]

Thanks!

[@iamdurgeshk]

What if r > n ? Let's say, n=6 and r=15. How would you do this then?

[@saikrishnabarupati7218]

Then change r=r%n

[@vishalpandyal853]

What if number of rotations are more than number of elements in array.

[@krishanakhatri8780]

Kindly make a video of block swap algorithm for array rotation.

[@AbhishekSharma-uh8pb]

where is the code for this program. can you please provide

[@damodaranm3044]

really cool explaination

[@NameXss]

Ok, how to rotate matrix, if min(m, n) % 2 == 0. min(m, n) / 2 is number of rings of matrix

[@ananthasubramanian7355]

Thank you

[@vatsalpagare6935]

In-place algorithm😊

[@atifbashir7229]

Nice job

[@raokshatri4515]

sir this is a left to right rotation. but also provide right to left rotation. thanks.

[@devidas4320]

Pls make videos on Fenwick tree

[@surenderlohia8227]

Wow...

[@ruchimishra2805]

nice video

[@181Ravikiran]

Can you add the code for it please, Thanks

[@fuadhasan0362]

thanks sir

[@akashjitnayak6947]

Awesome

[@meesamsyed8994]

Make a video for Matrix rotation

[@rachanadesai7984]

can you please share the code?

[@shabanashaik7135]

Sir! How to reverse the words of a sentences

[@unoop.]

shabana shaik To reverse the words of a sentence you could use similar technique... First reverse each word and the reverse the output. Eg. REVERSE WORDS OF A SENTENCE - - > ESREVER SDROW FO A ECNETNES - - > SENTENCE A OF WORDS REVERSE. Hope that helps

[@arvindgupta-zm7lz]

can you please provide the code

[@adarshkashyap8715]

Wow

[@CengizAkarsu]

********Here is Implementation of this theory in c Language*********** #include int main() { int n,arr[100],low,high,ele,rot,k; printf("Enter how many elements you want in your array "); scanf("%d",&n); printf("How many roations you want to perform "); scanf("%d",&rot); k = rot%n; for(int i=0;i

[@user-rq4hf8ti4d]

hello , who can help me to solve this question : Write a C++ program that reverses the order of a one-dimensional array of size 10 without using another array. Possible output: Original array is: 1 2 3 4 5 6 7 8 9 10 Reverse array is: 10 9 8 7 6 5 4 3 2 1

[@mohammedajazquadri7869]

execute the programs in system also sir plz

[@jagginadivya3680]

Tq sir... I got an idea on this right niw

[@ruchirsingh3635]

sir make a video on segment tree and binary index tree

[@vivekanandkhyade]

Yes sure Ruchir....in 2 days ....i will make video on Segment tree.

[@ruchirsingh3635]

thanqu sir

[@vivekanandkhyade]

hey Ruchir...I have uploaded the video on Segment tree.. Please check the video

[@rithikroosen2416]

i approached it in different way

[@leofun01]

Why it sounds so funny ?

[@suryareddy2171]

Rotateeft

[@cinemaismywife]

That is not O(n) ....it is O(2n)

[@MYUCOZ1]

It is considered as O(n) because we ignore the non significant variable.

[@unoop.]

greatavielite O(2n) ~ O(n) it's technically linear time

[@sundeepkaranam]

Its actually O(1n)....since array reversal can be done in O(n/2).....No more discussion about O(2n)........
