This is the only correct answer

Give us a reference implementation or I'll stab your homework.

Here you are. There's not much time left before the bird loses its temper!

        String input = "";


        while (true) {
            System.out.println("Type 0 for rock, 1 for paper, 2 for scissors, 3 to exit.");
            int playerChoice = scanner.nextInt();
            int computerChoice = random.nextInt(3);
            if (playerChoice >= ROCK && playerChoice <= SCISSORS) {
                int result = match(playerChoice, computerChoice);

lmao I wrote a 321 line program in python to do this ages ago

I'm a little less retarded now

It did at least save scores to a file but still awful

>>56249137

function rockPaperScissors(choice) {
  var outcome = ~~(Math.random()*3);
  switch(outcome) {
    case 0:
      console.log('You win!');
      break;
    case 1:
      console.log('You lose!');
      break;
    case 2:
      console.log('Tie!');
      break;
  }
}

Doesn't seen so menacing to me tbqh senpai...

>>56251355
Love it. The quintessential example of a black box program and a shitty set of requirements (rock, paper, scissors) to implement.

>>56249137
do it I no longer fear death or dying

>>56251355
I thought of a more compact way:

function rockPaperScissors(choice) {
  const outcomes = ['You win!', 'You lose!', 'Tie'];
  console.log(outcomes[~~(Math.random() * outcomes.length)]);
}

10 RANDOMIZE TIMER
20 PRINT "PLEASE ENTER (R)OCK, (P)APER, or (S)CISSORS"
30 INPUT C$
40 LET C$ = LEFT$(C$, 1)
50 LET P = 0
60 IF C$ = "R" OR C$ = "r" THEN LET P = 1
70 IF C$ = "P" OR C$ = "p" THEN LET P = 2
80 IF C$ = "S" OR C$ = "s" THEN LET P = 3
90 IF P = 0 THEN GOTO 20
100 A = INT(RND * 3 + 1)
110 ON A GOTO 120, 140, 160
120 PRINT "COMPUTER CHOOSES ROCK"
130 ON P GOTO 200, 180, 220
140 PRINT "COMPUTER CHOOSES PAPER"
150 ON P GOTO 220, 200, 180
160 PRINT "COMPUTER CHOOSES SCISSORS"
170 ON P GOTO 180, 220, 200
180 PRINT "YOU WIN!"
190 GOTO 230
200 PRINT "TIE!"
210 GOTO 230
220 PRINT "COMPUTER WINS!"
230 INPUT "WOULD YOU LIKE TO PLAY AGAIN?", C$
240 LET C$ = LEFT$(C$, 1)
250 IF C$ = "Y" OR C$ = "y" THEN GOTO 20
260 END

Due to probability, you could just program a random outcome anyway between lose, tie, and win. The user wouldn't notice the difference anyway.

I wonder if a compiler would optimize the game out.

>>56251260
Fuck man how do you even eat that many lines?

>>56251938
Not if you actually wrote the full game, compilers aren't smart enough to look at the "big picture" like that (if they were, we'd be using declarative rather than imperative languages much more frequently). Most optimizations just eliminate code that will never be reached, such as in the body of a

 while(false) { ... }

statement, or simplifying expressions like

if (x > 0) x = 0;

to

x = 0;

RPS <- function(x) {
    choices <- c("Rock","Paper","Scissors")
    if (identical(choices %in% x, integer(0)){
        stop("You fucked up")
    }
    playerChoice <- which(choices %in% x)
    
    computerChoice <- floor(runif(1,min=1,max=4))
    if (computerChoice == playerChoice) {
        print("Tie")
    } else if ( (playerChoice + 1) %% 3 == computerChoice) {
        print("Lose")
    } else {
        print("Win")
    }
}

>>56251917
Someone already did that in the thread above you.

>>56251917
that's boring though

technically 1 line

#include <stdlib.h>
#include <time.h>
#include <stdio.h>
int main(int argc,char *const argv[]){const char *o[]={"You win!","You lose.","Tie!"};char u, c;srand(time(0));while(u!='q'){printf("Please enter rock/paper/scissors or q to quit: ");u=getchar()|32;while((c=getchar())!='\n');(u=='r'||u=='p'||u=='s')?(printf("%s\n",o[rand()%3])):0;}}

I defend myself with crab.

sorry js doesn't have a universal input so interpret the argument as input and its return as output

a=a=>({1: 3, 3: 2, 2: 1}[a]==Math.floor((Math.random() * 3) + 1))?true:(a==Math.floor((Math.random() * 3) + 1))?'tie':false
