[How can I display if the letter is already input][1]

I'm trying to display and tells that the letter is already input and my problem that I wanted to display is already guessed when the letter repeats input by the user

I'd like to remove duplicates from several lists (in-place). Have tried the following but failed (Python Compiler):

Before I start, I'm not asking about binary search, or how to solve this problem.
My question is:
Why am I getting weird results. What's going on under the hood to cause these results?
Here goes:
I'm trying to write an algorithm to search an ordered list of words. The only catch is, the lexigraphically ordered list starts somewhere in the middle of the alphabet, and I need to find the rotation point (the index of the "smallest" word). To break the problem down, I decided I'll first search for the biggest word, which will always be right before the smallest, then I'll worry about the index.
I did this.
But then I started noticing weird results and got a little sidetracked.
I'm using an online interpreter and somehow I'm getting seemingly random results. I'm getting zi, yi, xi, wi,vo and sometimes d
Here's what my list looks like:
words = list({'vo', 'wi', 'xi', 'yi', 'zi', 'ai', 'bi', 'ci', 'd'})

and here's what my code looks like

I have a problem with function time.time(). I've written a code, which has 3 different hash functions and then it counts how long does they execute.

I'm practicing Java JSON programming using JSON-Simple on this site which says:

All the jars available in maven repo is supported.

UPDATE:

So I've now added the external maven library to project.

But I still can't get it work.

I tried

import com.googlecode.json-simple.JSONObject;

but got:

I have a list of expressions, in an array known as literals:

literals = ['-PacketAt(A)', '+CarAt(B)', '-CarAt(A)', '-PacketInCar', '+PacketAt(B)', '+CarAt(A)', 'LoadA', '+PacketAt(A)', '+PacketInCar', 'LoadB', '-PacketAt(B)', 'DriveAB', '-CarAt(B)', 'DriveBA', 'ProduceA', 'DischargeA', 'DischargeB']

I would like to remove the elements of the array that do not start with a + and - sign. I have written the following to try to do that:

I am trying to dockerize my NodeJs & Express API . In my API iam using https://www.npmjs.com/package/compile-run package to compile and run C, Cpp,Java,JavaScript(Node.js env), Python languages. This package requires all 5 compilers(gcc,g++,nodejs,python3,javac) installed on the server. If any compiler misses, it throws error.

In my local(undockerized) the API is working completely fine on both windows & ubuntu(As I have installed compilers on them).

I am trying to replicate the same on my docker image. But I am stuck.

Look at my Dockerfile:

when I tried to implement a linked list in visual studio 2019 using c it produces heap error. It was due to the free function. However, the code works fine on online compilers which use the GCC compiler. https://www.jdoodle.com/c-online-compiler/

I can't able to figure it out..........................

here is the code:

I tried compiling code using several IDEs of C++ using "graphics.h" header file using the list in TechGeekBuzz: Best C++ Online Compiler but they flag the error

1:21: fatal error: graphics.h: No such file or directory

The program I am trying to run is
