You are given three piles of casino chips: white, green and black chips in the form of an array. Each day you need exactly two chips of different colors to play at the casino. You can chose any color, but you are not allowed to use two chips of the same color in a single day.
You will be given an array representing the number of chips of each color and your task is to return the maximum number of days you can play.
Examples:
solve([1,1,1]) = 1, because after you pick on day one, there will be only one chip left
solve([1,2,1] = 2, you can pick twice; you pick two chips on day one then on day two
solve([4,1,1]) = 2
Brute force is not the way to go here. Look for a simplifying mathematical approach.
Tests:
solve([8,1,4])
solve([7,4,10])
solve([12,12,12])
solve([1,23,2])
Good luck!

Hello people who treat their finances with responsibility! Probably when choosing a broker you want to know answer to oanda scam? Oanda offers MT4 trading on its mobile and desktop apps. You can find these apps on the Google Play Store and the Apple App Store. We all know very well how strict moderation is in these companies. Moreover, in order to get into the list of applications that provide trading services, you must have licenses from the ministries of finance of certain regions, which the Oanda broker also has!
thanks for sharing!
C'est plus une opportunité cependant, de nombreux casinos offrent des bonus gratuits et sont plutôt bons, et c'est un très bon moyen d'essayer quelque chose de nouveau dans ce casino. J'essaie souvent de nouveaux casinos en ligne, mais avant de jouer, j'essaie de trouver des critiques à leur sujet. J'ai récemment lu une aperçu sur ce site et maintenant je choisis quel casino jouer car les bonus qu'ils y donnent sont plutôt bons. Si quelqu'un pense que les bonus offerts par les casinos sont une arnaque, alors ce n'est pas le cas. J'en ai été convaincu par ma propre expérience et je peux dire avec certitude que c'est encore l'occasion de comprendre le fonctionnement de ce casino.
Wow, this strategy suggests that you are a professional player. To be honest, I didn't even really understand what was at stake with these chips. I'm not a beginner, but I don't play often. Basically, I place bets and play spins on biggreenweek.com/id-ID/Home/. Sometimes I win, but not much because I don't make big bets. I'm terrified to make high stakes so as not to lose everything at once. I divide the invested funds into several different games and thus increase my chances of winning. You probably need to be a casino guru to understand where to put more dengue to get rich.

Hi, I am a student and I don't have many opportunities to earn money. After I moved out from my parents and stopped asking them for money, I began to think about how to earn money on my own. So, I can say that vulkanbet.me/ is the place where absolutely anyone can earn money.
Iβm a fairly busy person with office work and barely have the time to visit land-based casinos. Therefore, online gambling has always been my top choice. Especially, I'm not a pro gambler, so gambling online for free is always a fun way to relax. My favorite slot so far is probably NetEnt's Starburst slot, especially at this site, I can try it out in demo mode. What makes me love Casinomentor is that the free slots allow me to practice and have fun without worrying about losing my hard-earned money. Players can also check out various casino games and feature an overview of each gambling game at this site.
its all flash
it sucks
I think that many people like to play and win real money at the same time, especially when there are very real and transparent chances for this, because casinosanalyzer.com/free-slots-onl... provide not only a guarantee of complete security of the game in the online casino, but also unique methods and approaches to each player, play and you will see that it is possible.
