[M💙 Challenge] Grid Walking ⬛▪🏃▪⬛

Question

Monday Blue 💙 Challenge Series #6

Let's get moving this week! This time we will calculate the Euclidean distance from point A to B based on the path travelled on an unbounded grid.

💼 TASK
Write a program to accept a string to indicate the path travelled with the following symbol:-

[ N ] orth ⬆️
[ E ] ast ➡️
[ W ] est ⬅️
[ S ] outh ⬇️

and then output the straight-line (shortest) distance between the original position and final position. In case you're unfamiliar, you'll need to apply the distance formula from Pythagorean Theorem for this challenge. 😉

🔧 TEST CASE
"NE" 1.41
"WWW" 3.00
"NNNNN" 5.00
"EEENNNN" 5.00
"ENENENN" 5.00
"EEEWWW" 0.00
"SSWENNEW" 0.00
"SWSWSWSWSWSWSESWSESWSES" 13.00

❤ BONUS
Creative and clear-cut approach is encouraged.

Happy Coding!!! 😁💻

Answer 7

Again, glad you all enjoy the challenge! 😄

We got a few interesting submissions by now and I always believe there's a tradeoff between readability and performance.

For example, using native count approach will significantly shorten the code without if/else and switch but will force to scan the entire string up to 4 times (i.e. N, E, W & S) whereas a single scan can be done more efficiently by inspecting character one-by-one.

Let's see if we got any more submissions with unique approach until the next challenge. 😉

Answer 8

Glad you all enjoy the challenge! 😄

Answer 9

@Tuan Kiet Tran Good try! You may further improve the code performance by reducing the no. of iteration. 😉

Answer 10

By the way, congratulation to stay ahead of Sir Krishna's submission this time, I guess he's pretty busy today! 😂

Answer 11

@luka Nope it's purely my idea for the #MondayBlue challenge series.

I'll definitely give credit if I adopt the challenge from somewhere else. I'm happy to attach the link if anyone found any similar challenge or from other source too. 😉

Answer 12

@Swapnil Srivastava No late at all, #MondayBlue challenge best answer will be selected every week! 😉

Answer 13

@Pegasus Yes you may handle the exception if you prefer but it's safe to assume the string consists of character N, E, W and S only.

Regarding the decimal places, 2 is recommended but it's not mandatory as it's just for formatting purpose. 😉

Answer 14

Thanks everyone for your participation! I'm really glad to reach a new milestone of #MondayBlue challenge although I didn't make it into COTD with over 50 submissions.

I've read through all the codes and finally decided to pick VcC's Python solution which showcase the good use of lambda.

In fact, you all had done a good job so please don't feel bad if your solution didn't get picked as we still got more to come!

I hope you all enjoy and let's move on to the next challenge! ❤
