Link to this problem :

A message containing letters from A-Z can be encoded into numbers using the following mapping:

I have a large 'intend to take up most of the screen' component. If content within in this component is too large for the component, I want the component to have its own scrollbars, I don't want the page or the parent to develop its own scrollbars.

The best thing I've got for this is to use a flexbox on the parent to achieve this:

(Open full page)

I am confused and Im not sure what to do. The code below is stuff that I jotted down as I was thinking about the solution.

here is the question with example:

A message containing letters from A-Z is being encoded to numbers using the following mapping:

'A' -> 1 'B' -> 2 ... 'Z' -> 26

Given a non-empty string containing only digits, determine the total number of ways to decode it.

Example 1:

Input: "12" Output: 2 Explanation: It could be decoded as "AB" (1 2) or "L" (12). Example 2: Input: "226" Output: 3 Explanation: It could be decoded as "BZ" (2 26), "VF" (22 6), or "BBF" (2 2 6).

Updated question to include extra columns that pass from df1 to output, as well as add that the main df has 7 million rows.

I have two dataframes, similar to Pandas SO Question

And I need to multiply them where the names match. I'm not sure how to accomplish this cleanly. is there an apply function that does this easily?

DF1: (there are 16 columns of extra data, 7 million rows long)

I have Illumina paired-end reads contained within one .fastq file, denoted as '/1' for forward reads and '/2' for reverse reads.

I am using grep to pull out the individual reads and place them into 2 respective files (one for forward reads and one for reverse.

I already discussed how to manage devices in OneM2M on this topic but I noticed that I have still some misunderstanding.

1. Relation between MgmtObj and MgmtCmd. What is the exact correlation between them ? It seems MgmtObj keeps the status like the current software or firmware in it, the battery, device info etc. ObjectIds and ObjectPaths are used for mapping these information to a device management standard like LWM2M, TR-0069. Is it correct ?

2. I dont understand why Node has multiple reboot objects in it?

3. Lets assume we have multiple different firmwares on a node. Each firmware controls different part of the hardware. Then I guess I should create a MgmtCmd for each firmware but how a MgmtCmd knows which firmware (MgmtObj) its related for ? There is no link between them when we look at the resource definition in OneM2M. Actually this points to my first question that the relationship between MgmtObj and MgmtCmd because somehow when the MgmtCmd runs and finished its job then the related firmware should be updated in related Node.

4. Lets assume that I am not going to implement any device management standard like TR-0069, LWM2M etc. We are using nonOneM2M devices which has its own proprietary way of device management. Then whats the simplest way to do that ?

What we thought is, we should put some device management logic to the IPE(Inter proxy entity) which can subscribe to all the events that occurs in any related MgmtCmds for devices like update of its ExecEnabled status and creation of ExecInstance. Then we should notify the IPE with that ExecInstance then IPE manages all the procedure. Is it suitable to use Subscription/Notification mechanism for device management ?

The mgmtCmd resource represents a method to execute management procedures or to model commands and remote procedure calls (RPC) required by existing management protocols (e.g. BBF TR-069 [i.4]), and enables AEs to request management procedures to be executed on a remote entity. It also enables cancellation of cancellable and initiated but unfinished management procedures or commands.

The mgmtObj resource contains management data which enables individual M2M management functions. It provides a general structure to map to external management technology e.g. OMA DM [i.5], BBF TR-069 [i.4] and LWM2M [i.6] data models. Each instance of mgmtObj resource shall be mapped to single external management technology.

-------------------------------- CLARIFICATION --------------------------------

When we look at the xsd of node, it contains child resources like

• List of firmwares
• List of softwares
• List of reboots
• etc...

Actually I just made up an example, its not a real world scenario. Also I try to understand why node has multiple of those resources like reboot, software, even if deviceinfo seems weird. What they refers ?

I currently have a GridPane as the root of the layout and I have another GridPane inside it that contains 2 Labels. I'm trying to have 1 of these labels left-aligned and the other right-aligned.

I have tried using GridPane.halignment="RIGHT", but that has no effect on the Labels.

This is the layout I currently have:

This is the layout i want:

The code for my layout looks like this:

So the problem being asked is:

A message containing letters from A-Z is being encoded to numbers using the following mapping:

I am working on problem where I need to decode a string..

A message containing letters from A-Z is being encoded to numbers using the following mapping:

'A' -> 1

'B' -> 2

...

'Z' -> 26

Given a non-empty string containing only digits, determine the total number of ways to decode it.

Example 1:

Input: "12"

Output: 2

Explanation: It could be decoded as "AB" (1 2) or "L" (12).

Example 2:

Input: "226"

Output: 3

Explanation: It could be decoded as "BZ" (2 26), "VF" (22 6), or "BBF" (2 2 6).

I came up with below recursion approach but it is giving wrong output for this input "227". Output should be "2" but my program is giving "3":
