✅ Declaring a Dictionary as a Member Variable

Trying to define a dictionary as a member variable in a class. Getting this error:

Array initializers can only be used in a variable or field initializer. Try using a new expression instead.
Can only use array initializer expressions to assign to array types. Try using a new expression instead.

✅ Advent of Code Day 1 - Issue with Chars

For this problem, you essentially have to find the first and last digit contained in each line, so for a line 271lonepxp2flbmbz the first digit would be 2 and the last digit 2 as well. Put 'em together, you get 22. Now you have to find that value for each of the 1000 lines provided and add them all together.

string input = """
9sixsevenz3
seven1cvdvnhpgthfhfljmnq
6tvxlgrsevenjvbxbfqrsk4seven
9zml
""";

int sum = 0;
foreach(string word in input.Split())
{
    List<int> nums = [];
    foreach(char ch in word)
    {
        if(Char.IsDigit(ch))
        {
            nums.Add(Convert.ToInt32(ch - '0'));
        }
    }

    int firstNumber = nums[0];
    int lastNumber = nums[^1];
    int fullNumber = firstNumber * 10 + lastNumber;
    sum += fullNumber;
}

Console.WriteLine(sum);

string input = """
9sixsevenz3
seven1cvdvnhpgthfhfljmnq
6tvxlgrsevenjvbxbfqrsk4seven
9zml
""";

int sum = 0;
foreach(string word in input.Split())
{
    List<int> nums = [];
    foreach(char ch in word)
    {
        if(Char.IsDigit(ch))
        {
            nums.Add(Convert.ToInt32(ch - '0'));
        }
    }

    int firstNumber = nums[0];
    int lastNumber = nums[^1];
    int fullNumber = firstNumber * 10 + lastNumber;
    sum += fullNumber;
}

Console.WriteLine(sum);

This is my code. However, I just keep getting an Index Out of Range error on the line that says int firstNumber = nums[0]; and I just don't get why. I originally had the code a lot more condensed but I expanded it to debug and that appears to be where the issue is. Naturally I initially thought that nothing was being added to the array, but so far I can't figure out why that would be. I'm going to go and Console.WriteLine nums right now to see if it actually contains anything, but either way I'd appreciate it if someone could help me see what I did wrong here.

Absolute Beginner - Accessing Variables From Other Classes

Hi. DecodeButton.cs:

using UnityEngine;

public class DecodeButton : MonoBehaviour
{
    void Start()
    {
        Decoders decoder = new Decoders();
    }

    void OnClick()
    {
        Decoders.CaesarCipher(ReadStringInput.input);
    }
}

using UnityEngine;

public class DecodeButton : MonoBehaviour
{
    void Start()
    {
        Decoders decoder = new Decoders();
    }

    void OnClick()
    {
        Decoders.CaesarCipher(ReadStringInput.input);
    }
}

ReadStringInput.cs:

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ReadStringInput : MonoBehaviour
{
    public string input;
    
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    public void ReadInput(string s)
    {
        input = s;
    }
}

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ReadStringInput : MonoBehaviour
{
    public string input;
    
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    public void ReadInput(string s)
    {
        input = s;
    }
}

In DecodeButton.cs, I'm getting the error CS0120 about Object references but frankly I'm not understanding it. Can someone help me out?

✅ Calculating Remaining Processing Time?

Let's say I'm running a bunch of loops and searching long arrays - essentially some task that will take, let's say, 10 seconds on average. How can I calculate the amount of time remaining to complete the calculation to show to the user of the app?

✅ .Split() Returning Spaces Between Words in String[]

Hi. I have an string array string[] strArr of words in format [word1, word2] and so on - just a basic format.. I got that by performing .Split() on another string, let's say string x. x was in format

"""
word1
word2
"""

"""
word1
word2
"""

and so on, for 30,000 lines. Now that I've converted this all to an array, how can I print the array such that the Console output would be ["word1", "word2"] etc.? I want to initialize strArr instead of performing .Split() everytime my app starts.

✅ Split Lines into Array Elements

I've got a list of common English words in the format

word1
word2
word3
word4

word1
word2
word3
word4

And so forth. How can I split this into an array of format `string[] arr = {"word1", "word2", "word3", "word4"}. I imagine this would be done with .Split() but it's not working for me.

✅ Foreach Loop Printing Multiple Chars from a String Simultaneously

string s = "Hello World";
foreach(char ch in s)
    {
         Console.WriteLine(ch);
    }

string s = "Hello World";
foreach(char ch in s)
    {
         Console.WriteLine(ch);
    }

Prints

He
l
l
o
 
W
o
r
l
d

He
l
l
o
 
W
o
r
l
d

Surely H and e shouldn't be printed on the same line? What am I misunderstanding here?
