Progression | Chronicles my progression over nine-weeks to learn | Learning library

So I have the following data below, so basically every column after tree is a progression of the value of it's values(e.g Tree_0, Tree_1 and etc.)

I'm trying to make a simple recursive code that counts the sums of a fibonacci progression but I don't know how to make the counter works properly, this is my code:

Question : Can i realize method private void fillingArrayList() use Java Stream API (that is in one line) . The variable i is needed to define a length of String ; I try a for each loop but it doesn't work . I need a range for loop.

I'm trying to create a component Button that can help me navigate between stacks. I use react-navigation to navigate in the app. The problem is that I have 3 files :

-App.js

Given N consecutive integers from 1 to N.

Count the number of ways to choose a number of numbers (at least 1 number) such that they form an arithmetic progression (AP) modulo 1e9+7

Define L[N] is the answer

The number of APs which begin with 2, end with N = The number of APs which begin with 1, end with N-1

The number of APs which begin with 1, end with N is the number of divisors of N-1 (=\tau(N-1))

So, L[N] = L[N-1] + \tau(N-1)

But N <= 10^10 . The algorithm must be O(n), how can I calculate \tau(n)?

This code prints a simple progression, doing one thing at a time:

I have a function, in this case a function which says if a list with numbers forms an arithmetic progression.

I have a dataset that produces a sinusoidal wave when put in a chart. Let us imagine that every day around 9AM, my chart hits the lowest point of the day and starts to go up. And around 6PM it reaches the highest point. I need to count (from 9AM to 6PM when my value is increasing) how many times my value is greater than or equal to the previous one and how many times my value is lesser than the previous one.

Let us take 11 values: [4-4-5-6-5-6-5-6-7-7-8]. I have 8 values that are greater than or equal to the previous one. And only 2 lesser that the previous one. The idea is to be able to say, during that period I have had 8 positive values for a progression of 4 (from 4 to 8). It means that on average, a positive value gives me 0.5.

Important note: I am using BigQuery

Here is my query so far:

Reported to Qt as a bug: https://bugreports.qt.io/browse/QTBUG-93475

I am re-drawing a QPixmap multiple times in different locations, with differnt rotations by transforming the QPainter. In certain situations the QPixmap is not drawing correctly. The GIF below shows my initial discovery of this issue with a QPixmap containing a green cylinder, notice how the rendering behaves as expected to the left of the GIF, but there is a boundary beyond which the rendering is incorrect. The QPixmap content appears to stick in place, and the pixels at the edge appear to smear out accross the rest of the pixmap. In the GIF there is a magenta background to the QPixmap, this because the targetRect used by QPainter::drawPixmap() is also beuing used to seperately fill a rectangle underneath the pixmap, this was because I wanted to check that the target rect was being computed correctly.

To keep things simple I am simply filling the QPixmap with magenta pixels, with a 1 pixel wide transparent edge so that the smearing causes the pixmaps to dissapear completely. It doesn't show the image "sticking" in place but it clearly shows the boundary as beyond it the pixmaps seem to dissapear.

I have been experimenting with this myself and I believe this to be entirely caused by the rotating of the QPainter.

The angle of rotation seems to have an effect, if all of the pixmaps are rotated to the same angle then the boundary changes from a fuzzy diagonal line (where fuzzy means the boundary for dissapearing is different for each pixmap) to a sharp 90 degree corner (where sharp means that the boundary for dissapearing is the same for all pixmaps).

The range of different angles also seems to play a part, if the randomly generated angles are in a small 10 degree range, then the boundary is just a slightly fuzzier right angle, with a bevelled corner. There seems to be a progression from sharp right angle to fuzzy diagonal line as the number of different rotations is applied.
