ISx | Scalable Integer Sort application for co-design | Database library

I'm finding this problem hard to search about because the terms summarize, groupby, rearrange, table are just so generic.

What I'd like to do is summarize a value after grouping by exactly two factors, and put the result in a table with rows/columns as factor1/factor2. This is a special case of groupby-exactly-two with one value per cell, but I find myself wanting this pattern a lot.

Here's a toy data set where factor "isx" has two levels and factor "grp" has three levels:

Since I am a non-English speaking person, I am not familiar with English.

The black line drawn by hovering over is not selected, but the gray line created when the coordinates are first created is selected.

As you can see from the code, I initially declared selection: false when initializing the code. There is no other code to manipulate the selection, so I deleted it for readability.

Here is my code

I'm trying to replace java for loop with a lambda.

I have at first a class Arrs:

I am making a pacman arcade game on Java but my collisions have problems. If you see my image here my pacman sprite stands still (no x or y movement) when visiting a corner or when trying to turn back the direction it came (ie goes left but does not go right again). I understand this is because I set my xMovement to 0 and yMovement to 0 if a collision is detected (see second code block under collide()).

How would I allow the pacman sprite to move the other way (ie it comes from the left and I want it to go right) or traverse a corner if my collision() does not allow this?

Below is my draw method in the App.java class which draws the player based on the user's input. The keys wasd correspond with up, left, down, right respectively. this.direction is only used so the player does not waste a move nor go through a wall when a collision happens. *Note, I put (this.player.x_ord + 2) % 16 == 0 because my pacman image is not a 16x16 image unlike my walls which are.

I have deriving two separate groups from a list, error data and error free data:

I'm attempting to create a MiniMax algorithm that will calculate the best move for a game of Tic Tac Toe. I have attempted to write this in multiple ways and I keep getting an infinite loop. Any idea what I'm missing here?

Here's the code that is used to traverse the game board and calculate the best move using MiniMax:

In the following code sample, my goal is:

• Let obj.isX be true when obj constructed by type A
• Let obj.isX be false when obj constructed by type B

I'm having trouble implementing internationalization of DateFormat.

I use the below code to get the date formatted:

I am using Intellij's Java to Kotlin converter.

When converting a function like this (in this example it is an overriding function but this also applies to non-overriding):
