[M💙 Challenge] Number Squeezer 🤜🔢🤛

Question

Monday Blue 💙 Challenge Series #12

Let's have some exercises this week! This time we will squeeze a number list from both directions until we get a single integer sum.

💼 TASK
Write a program to accept a number list and display the output for each iteration of the squeezing operation with following conditions:-

✔️ The outermost integers from left and right will be squeezed and sum together after each iteration
✔️ When the number list have less than 4 elements, the next iteration will produce a single sum and the process stops.

🔧 TEST CASE
[ 1 ] ➡
1

[ 1, 2 ] ➡
3

[ 1, 2, 3 ] ➡
6

[ 1, 2, 3, 4] ➡
3, 7
10

[ 1, 2, 3, 4, 5 ] ➡
3, 3, 9
15

[ 1, 2, 3, 4, 5, 6 ] ➡
3, 3, 4, 11
6, 15
21

[ 1, 2, 3, 4, 5, 6, 7 ] ➡
3, 3, 4, 5, 13
6, 4, 18
28

➕ EXTRA
Accept an additional integer which determines the squeeze factor that indicate the numbers to be compressed for each iteration. The examples shown above have a squeeze factor of 2. Besides, it's easy to observe that the iteration will stop if the number list consists of less than {2 × squeeze factor} numbers.

❤ BONUS
Clear-cut and optimized approach is encouraged.

Happy Coding!!! 😁💻

Surely the smallest and most comprehensive solution using recursion :D

Answer 2

Nice challenge. I will make.
Edit : I have made ⬇

Answer 3

My try

(yesss!!! I finally posted at the right time !!!)

Answer 4

My code require two inputs, the first is the list of numbers, which are to be separated with comma, example :
1,23,4,5,11,3 and the second input, is the factor(as demanded by Zephyr.

Answer 8

@Kinshuk Ok thanks for telling.

Answer 9

By the way, @Zephyr How do you post questions with more than 512 characters? 😀😅😲

Answer 11

@Aayush I'm not as smart as you think but I believe the people here who submitted the solution are the smart one.

Take your time and treat it as an exercise to flex your brain muscle. You'll become a better problem solver along the thinking process! 😉

Answer 13

Thanks everyone for your interest and help to clarify the problem. 😄

Yes a squeeze factor of 1 will cause an infinite loop in this case as we will never get a single sum.

Python seems to be the most preferable choice for this challenge and perfect when combined with recursion! 😄

Answer 14

@Kinshuk I think the squeeze factor must be greater than 1 or else it will be an infinite loop.

Answer 15

My Try With ArrayLists

Answer 16

@Yash Thatte It will be available in 20 mins, stay tuned! 😉

Answer 17

Thanks everyone for your participation! I had an emotional roller coaster this week due to the overwhelming response from COTD and fortunately I'm able to spare my time to review the submissions.

We got a few interesting submissions this time with elegant recursion and even an animated visualization via HTML too by Jonathan! (This was featured @ SPECIAL MENTION on top)

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

Answer 18

Your Monday Blue Challenges Require Me to Sit Down And Think ... I am still working on the bouncing ball physics ... You're smart 👍

Answer 19

@Kinshuk..
you are right

Answer 20

Me knowing Java requires a 50-100 line code whereas Python programmers sum up everything in 10-20 lines
