Your task is to find number of ways in which we can reach from point 'A' to point 'A' in n-steps .
'n' will be provided as the user input .

Example : input : 3
output : 6
[ABCA,ABDA,ACBA,ACDA,ADBA,ADCA]

Answer 1

sorry buddy but thats wrong
@Sayan

Answer 2

challenge is to find number of ways
//if U show paths also ... then it would be gr8 👍

EDIT: Fixed a couple bugs, should be functioning now :)
EDIT 2: Thanks for marking mine correct 😄

How I decided to go about this was to try and actually find out all possible paths, using a recursive function. And I have to say, It was pretty fun 👍

Answer 4

nice @Cestpasgrave
//me too not done with any formula first ... then noticed can also be done by combination .

Answer 5

and I like a code or a helpful answer , rather than a unuseful answer@Sania
// and @Tomas , the challenge is little bit different ... read carefully

Answer 6

@Oma try again
for input : 6
output : 183

Answer 7

nice code ☺ ... U can make it perfect
// 2nd last letter must not be A , else U can use A in between

Answer 8

//have a look on this also , made by eliminating some cases
//& yes its also a 1-LINER recursion

Answer 9

@Sayan Chandra ,
here the biggest advantage is SYMMETRY
//there was symmetry in tetrahedron , same in case of triangle ... thats what made it so small ...[👉 ie we can go to any of the other points from a point]
//okh, bye guys ... will come later [nice talking with u]

Answer 10

Hello Gaurav,

I found a formula.

Could you check if results are okay please?

Answer 11

hi @Adylbek ,
my post is not 4 chat purpose ... sorry
//If U have some question/doubt , then create a separate thread for that , would like to help U out

Answer 12

@Sayan ,
yes its correct now ☺

Answer 13

and why not as alternating row

Answer 14

where is the explanation @Oma 😂
// I think I got it

congrats🎊✅ @/*Unknown-name*/ 4 best answer marked
//for answering fast & with paths 👌☺

Answer 15

nice try & thanks for participating @Sylar , but not correct
//U can have a look at outputs for more possible inputs

I inputted 4 , but output was showing E in a path (but a tetrahedron have only 4 vertices)

Answer 16

@Oma looks correct to me ☺
//yes that correct 👍

//& @cab. , mix ... remove your unmeaningful answers

Answer 17

not so ugly recursion

Answer 18

@sayan thats the result after 24h .... not bad!

Answer 19

@Gaurav post this as assignment in Lessons Factory 👍
