UP

The program is now 100% bug-free !
Thanks to Bisam for some great optimisations ! :thumbup:
A TI-82 Stats/TI-83 version is now included !


New code: (version 83+/84+):

Version 82 stats/83:

Thanks !

I don't understand your code, but thanks, that will be very good enough !

Sorry for interrupting the conversation (Soulthym ? Un étudiant français qui fait du Grammer ? Serions-nous deux ? ), but I have an idea...

I saw what you have done with your app 'Tutor' Xeda, and I thought it could be very useful in Grammer.

I explain:
Imagine the user sets a list of keycodes that would be automatically pressed the next time the calculator will be waiting for a signal from the keyboard, we could make:

• pre-recorded answers to Inputs
• cheatcodes in games to control automatically the player/object-to-move
• We could use this to allow the player to make tiny macros in a game, without modifying the source code

In the same way, but much less useful because it can be easily done yet with getkey, create a function that records what key are pressed to make an history.

With this two functions, the user could record a manipulation and re-do it many times automatically.

Thanks . Does anyone see 'INVALID DIM' errors ?

Hey everyone, here is the program I made to win the TI-Concours 2013, 1st round, Basic z80

Unfortunately, I'm only 4th    because the jury said there was DIM INVALID errors in the program.
But I can't find them, so please try it, and tell me where they are...

Like I said, it's a mastermind game, running well on TI-82/83/84 (choose the right program: 83p/8xp ).
It's only 4000 bytes, like the TI-Concours wanted. (3139+767+94=4000, I'm a math god ! program+pic+list)

features:

• 2 players mode
• IA mode
• 4 levels of difficulty (the number of digits increases (from 5 to 9), and the number of 'colours' to find too (from 3 to 6))
• You can allow or not codes with several same colours
• High score saved in each game mode
• Answers can be placed or not. (If not, the program tells you that you have 3'+' and 1'°' for example, but not which ones), like in the real mastermind game.
• Awesome graphics, sure.
• Source included with comments (see here)
  

Please, try it, and give me some feedback !
Thanks a lot !

Hello everyone,

It has been time TI-Planet have not organized a contest, and here is the lack filled
So we organize a contest, about 5 weeks, well mixing arithmetic and algorithmics.


Introduction:
In mathematics, a prime palindom number is a number which is both prime and palindromic.

A prime number is an integer that only admits two positive and integer divisors (which are 1 and itself).
This definition excludes 1, which has only one positive and integer divisor ; it excludes 0 too, which is divisible by all the positive integers.
For example 6 = 2 × 3 is not prime and 21 = 3 × 7 or 7 × 3 either. But 11 is prime because 1 and 11 are the only divisors of 11.
So, the prime numbers are, in order, 2, 3, 5, 7, 11...

A palindromic number is a number whose writing (in base 10) is read in the same way from left to right and from right to left.
For example, all the 1-digit numbers are palindromic: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
The 2-digit palindroms are: 11, 22, 33, 44, 55, 66, 77, 88 and 99.
101 is a 3-digit palindromic number.

So, the prime palindromic numbers are: 2, 3, 5, 7, 11, 101, 131...

Subject :
Make a program fastest as possible to find the n-th prime palindromic number.

Plateform :
The candidate will perform its participation:

• TI-Nspire
• TI-82Stats/83/76
• TI-83+/84

Categories:
The candidate's production will be judged in one of those categories:

• TI-Nspire
• TI-82Stats/83/84/76

Languages :

• TI-Basic Nspire
• TI-Basic TI-82Stats/83/84/76
• TI-83+/84 Assembly NO SHELL (So, you can participate with Axe compiled for no shell)
  
• TI-82Stats/83/76 Assembly NO SHELL

NB: on TI-82Stats/83/84,TI-Basic and assembly combinations are allowed.

Constraints :
On TI-82Stats/83/84/76, the program will catch n in the 'Ans' variable, and will send the nth prime palindromic number as a result in Ans.
For example, to obtain the 42th prime, we will type:

• TI-Basic program: 42:prgmPALPREM
• TI-83+/84 Assembly program: 42:Asm(prgmPALPREM
• TI-82Stats/83/76 Assembly program: 42:Send(9prgmPALPREM

In each case, the program should send the result 18181 in Ans, reusable in the home screen for calculations.


On TI-Nspire, the main program should be a function which take the n parameter and which sends the result. For example, palprem(42) should answer 18181.

YOU MUST NOT USE a pre-calculated list of prime palindromic numbers in your program, directly under penalty of disqualification.

YOU MUST NOT USE functions like isPrime() which would provide a direct response, it destroys the value of algorithmic thinking, and it would be unfair to those who don't have this function... ;)

The program MUST run on not-CAS TI-Nspires.

Notation :
The final score will be on 20 points, and the scale is as follows:

• 3 points for the proper functioning of the program
• 10 points for the fast execution of the program (it will be tested and compared to competitors on identical machines with identical languages)
• 3 points for the respect of the rules
• 4 points for an explanation

Jury :
Participations are rated on an equitable basis according to a common scale by a jury whose composition is as follows:

• Adriweb
• Critor
• Laurae
• Levak
• Lionel Debroux

When ? :
The contest starts Monday the 1st of April 2013 and finishs Sunday the 12th of May, 23h59 (GMT+1)

How ? :
To participate, candidates must send to the email address [email protected] :

• complete mailing address with first and last name
• a valid email address for contact
• the expected production (8xp, 83p, tns)
• any other information or file deemed useful by the candidate concerning its production

The e-mail correctly send is taken as an entry.

Lots :
Through our partnership with TI-France and Jarrety, the winners of the contest (one winner per category) will be rewarded with:

• 1st price: 1 calculator + 4 TI-Planet stickers
• 2nd price: 1 poster TI + 3 TI-Planet stickers
• 3rd price: 2 TI-Planet stickers

1st price in the Nspire category: a TI-Nspire CX (not CAS)
1st price in the TI-82/83/84 category : a TI-84 Pocket.fr

Complete rules:
The complete rules for this contest, legally registered to an usher, are available on
TI-Planet or the  UPECS website. (French)


See you soon on TI-Planet !

PS: I know I'm a bit late, because the contest has started...

I have one question:
What does the "TI-84+" option enable ?
It's just to adjust the timing while pause moments ?
