Java is widely used in enterprises, it's definitely not going away anytime soon. You can use java for web dev as well. So it's upto you to decide. More on reddit.com

Rust 2022 Day 07 Burnt a lot of time and sanity trying to build a traditional tree in rust. In the end I used a solution similar to an ArenaTree, a Vector of directories with the index of the parent. Inspired by u/raui100 More on reddit.com

Python. Part 1, Part 2

Time to break out the regular expressions (for input parsing). This is also where I learned that if you're reading line by line with fileinput, you can't stop and resume processing in a second loop. It's all gotta be done in a single for loop. So, I turned what would've been two simple loops into one loop with a state variable, which calls one of two different functions depending on which state we're in.

Crate stacks are stored as lists. So, it's a list slicing day.

In part 1 I initially had the wrong answer because I thought we were grabbing all the crates at once and preserving that list. Turns out I had to reverse the list first. And then for part 2, don't reverse it. (My initial solution for part 1 would've been right for part 2.) So once again, part 2 is simpler than part 1.

Also learned that you can't have a variable named "from" in Python.

Okaay, I'm a beginner, I just started learning javascript in september this year. No previous programming / coding experience before, ZERO. I'm going slow at my own pace but I'm trying, i did what made more sense to me for my level hehe... so: first part: const smallInput = ****here goes the input***; let regex1 = / /g; function deleteSpaceBetweenLetters(textInput) { let noSpaces = textInput.replace(regex1, ""); return noSpaces; } const inputWithoutSpaces = deleteSpaceBetweenLetters(smallInput); // console.log(inputWithoutSpaces); let textToArray = inputWithoutSpaces.split("\n"); // console.log(textToArray); // puntos const A = 1; const B = 2; const C = 3; const X = 1; const Y = 2; const Z = 3; const DRAW = 3; const WIN = 6; let oponentMovePoints = 0; let myMovePoints = 0; function determineWinner(array) { for (let i = 0; i < array.length; i++) { if (array[i] ==="AX") { console.log("It's a draw"); oponentMovePoints += A + DRAW; myMovePoints += X + DRAW; } if (array[i] ==="AY") { console.log("Y wins"); oponentMovePoints += A; myMovePoints += Y + WIN; } if (array[i] ==="AZ") { console.log("A wins"); oponentMovePoints += A + WIN; myMovePoints += Z; } if (array[i] ==="BX") { console.log("B wins"); oponentMovePoints += B + WIN; myMovePoints += X; } if (array[i] ==="BY") { console.log("It's a draw"); oponentMovePoints += B + DRAW; myMovePoints += Y + DRAW; } if (array[i] ==="BZ") { console.log("Z wins"); oponentMovePoints += B; myMovePoints += Z + WIN; } if (array[i] ==="CX") { console.log("X wins"); oponentMovePoints += C; myMovePoints += X + WIN; } if (array[i] ==="CY") { console.log("C wins"); oponentMovePoints += C + WIN; myMovePoints += Y; } if (array[i] ==="CZ") { console.log("It's a draw"); oponentMovePoints += C + DRAW; myMovePoints += Z + DRAW; } } return "The end" }; const results1 = determineWinner(textToArray); console.log(results1); console.log(); console.log("The oponent's total amount of points is:"); console.log(oponentMovePoints); console.log("My total amount of points is:"); console.log(myMovePoints); second part - only showing the changes : (i just copypasted what i had into another file and adjusted it. I'm sure everything can be done in the same file but i had no clue, so i did what i could :P ) const rock = 1; const paper = 2; const scissors = 3; function determineWinner(array) { for (let i = 0; i < array.length; i++) { if (array[i] ==="AX") { console.log("I lose. I need scissors"); oponentMovePoints += A + WIN; myMovePoints += scissors; } if (array[i] ==="AY") { console.log("It's a draw. I need rock"); oponentMovePoints += A + DRAW; myMovePoints += rock + DRAW; } if (array[i] ==="AZ") { console.log("I win. I need paper"); oponentMovePoints += A; myMovePoints += paper + WIN; } if (array[i] ==="BX") { console.log("I lose. I need rock"); oponentMovePoints += B + WIN; myMovePoints += rock; } if (array[i] ==="BY") { console.log("It's a draw. I need paper"); oponentMovePoints += B + DRAW; myMovePoints += paper + DRAW; } if (array[i] ==="BZ") { console.log("I win. I need scissors"); oponentMovePoints += B; myMovePoints += scissors + WIN; } if (array[i] ==="CX") { console.log("I lose. I need paper"); oponentMovePoints += C + WIN; myMovePoints += paper; } if (array[i] ==="CY") { console.log("It's a draw. I need scissors"); oponentMovePoints += C + DRAW; myMovePoints += scissors + DRAW; } if (array[i] ==="CZ") { console.log("I win. I need rock"); oponentMovePoints += C; myMovePoints += rock + WIN; } } return "The end" }; More on reddit.com
