stacks | System Stacks for Linux * OS are a collection of production | GPU library

I am working on a React project and am trying to convert a blob of JSON into JSX markup.

I have this code working, but it only seems to render the very first item. I am unsure how to get it to return the required, entire stack.

The JSON blob would look something like this:

I have the following call to Firebase database. If I want to share the result of the observable, where I'd I put the share really(1) ?

I am reading Adam Drozdek's book on DSA, and in solving the mouse in maze problem, he is using stacks. But how would I (if i wanted) count the number of steps the rat takes ? Because according to his stack solution , false positive neighbors (ie. the neigbors that failed to reach destination) also get marked, and there is no backtracking which unmarks these cells. Pls help me. Pls.

EDIT: his algorithm

After not succeeding in solving my problem here, I had to create a new question with all my classes in it.

I am new to react native and have a problem figuring out how to navigate from one class to another one with passing parameters and would appreciate your help.

All I want to do is:

1. SessionCreate with flatlist containing CustomButton
2. Navigate from SessionCreate to ItemConfig by clicking CustomButton
3. Pass parameter "element" to ItemConfig
4. Show content of parameter passed in ItemConfig

With this setup an empty "element" is passed as parameter to the ItemConfigScreen (but no error occurs):

When I deploy a cloudformation stack to AWS I got this error message:

I'm trying to create a stacked bar chart where the important sub categories are represented by a label, but the smaller sub categories don't appear (as this would really clutter the chart). I've now made a subset to only display labels where the value is over 20 for that sub category, but some of the labels are not centered correctly even though I've used position = position_stack(vjust = 0.5)

EDIT: for example of labels which are centered correctly, see the 'housing' column, where property rates doesn't sit within its stack - its actually on a line between 2 stacks. Another example is in the 'Miscellaneous' column, where insurance is correct, but 'personal care' should be higher up, in the larger stack.

If anyone has a better way of displaying these labels that would also be appreciated as I'm not really happy with how this chart is going to look even if the labels do center properly, but i just cant think of a better way to do it.

here is my code for the graph;

This is my code:

This very basic app with a single stack navigator doesn't behave as expected for web. On iOS/Android the header stays in place and the screen scrolls under the header. For web the header doesn't stay fixed on top. See this snack https://snack.expo.io/@tositsa/nested-stacks-fixed-header-issue-2

I think this might be a bug in react-native-navigation or react-native-web, but I'd love to see if there is a workaround somehow.

I am learning to create stacks using cloud formation template, I am trying to create an EC2 instance using cloud formation template with security groups so I can ssh to it as well. My cloud formation template is :
