Daily Challenge #74

I want you to install this app and try to figure out how i did this. Make your own version and show your blocks. I will post my blocks tomorrow.

This is how it looks when you run the apk.

The goal is simple. Pick a number between 1 and 63 and check all checkboxes of the columns where you can find the number you picked. After that click the guess button and the app will tell you which number you picked.

I used 60 blocks to make it work. The formula where it guesses your number is only 18 blocks.

Good luck!!!

0h! I have seen this puzzle before, but never put it on koding. But unfortunately, I don’t have my pc right now until like 8 hours later.

Peter · May 27, 2020, 4:02pm

I will wait at least 26 hours until i post my blocks.

Peter · May 28, 2020, 5:14am

Little tip: By adding 1 block i made a version where you have to check all the checkboxes of the columns where you can not find the number you picked and it still works.

I think I got the logic behind this challenge but not able to block it

Peter · May 28, 2020, 6:15am

Maybe you can tell the logic here?

This can help others

Vaibhav · May 28, 2020, 6:16am

Yes exactly its related to decimal to binary conversion

Peter · May 28, 2020, 6:33am

I didn’t use that in my formula but i would like to see how it would work.

This is my text that i used.

Hi @Peter
Your challenge remembered me of my childhood days.I have played that game with my friends.The main motive to play this game was to represent ourself as a magician who reads minds.

I think you have used for each loop and if else condition to check that which number is common in checked lists.
I will try to solve your challenge

your previous post explains all

Vaibhav · May 28, 2020, 6:44am

Yes where we would ask the other person to think of a card from the cards arranged 3*3 format and then asking whether the card is in which column and row. Am I right? @vknow360

vknow360 · May 28, 2020, 6:46am

You are a magician @Vaibhav

Peter · May 28, 2020, 6:52am

Nope, that would make a lot of blocks i think. Like i said to calculate the guessed number i only used 18 blocks.

Peter · May 28, 2020, 6:54am

I know my image explains all but how would that look in blocks? That’s the challenge.

vknow360 · May 28, 2020, 6:54am

Here is the solution:

addition of numbers of first row of given lists

WatermelonIce · May 28, 2020, 6:57am

Um… a quite straightforward answer

Solution

Label1.Text:
1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63
Similar thing for other label.

So Label1.Text is to be entered manually? And if so, it’s ok if we arrange the layout manually? I thought we also have to do this with blocks. I guess I am making this complex for myself. . May be @Peter can tell something about this…

WatermelonIce · May 28, 2020, 7:07am

Yes

you can, it’s just if the texts have to be shown in the layout, why don’t we use the text in the block?

My layout looks like this

Peter · May 28, 2020, 7:08am

In my solution labels are also filled with the help of blocks. You can fill them manually if you want but that is a lot of work.

This is my designer

Good try.
Did you test your solution? I count 29 blocks in total on the screen and you haven’t done the others. I have 18 blocks for the entire formula. mmmmm this emoji even looks like me.
