            How to match strings between two columns in R?
            Asked 2021-Jun-13 at 09:09

            I want to create a new column (MATCH) on the basis of string match between two existing columns. For example -

            st_add aa_add MATCH jai maa durga society jai maa durga colony MATCH elph road highway 1 road highway 2 elph MATCH srinivan colony parel ist srinivan bus depot NOT MATCH

            If there is a match in three or more words between column 1 and column 2 then then column 3(MATCH) should show "MATCH". But if there is less than 3 words matches or no match at all (example row 3) then the result should be "NO MATCH"

            Answered 2021-Jun-07 at 13:19

            There are a few things that make this question a little difficult to answer, but I believe the below will get you pointed in the right direction.

            1. You don't include the GET_JSON method, so your example isn't complete and can't be used immediately to iterate on.
            2. In the example you bring, there isn't a name property on the objects contained in the releases array. I substituted name with title below to demonstrate the approach.
            3. You state

            Moreover, I'd like to say that if, for example, the name of a release is similar to that of a previous one already present, the entire object is not added to the new array.

            But you don't define what you consider that would make releases similar.

            Given the above, as stated, I assumed you meant title when you said name and I also assumed that what would constitute a similar release would be one with the same name/title.

            Assuming those assumptions are correct, I just fetch to retrieve the results. The response has a json method on it that will convert the response to a JSON object. The I map each release to the smaller data set you are interested in(id, title) and then reduce that array to remove 'duplicate' releases.

            QUESTION

            Calculate longest consecutive traversal possible
            Asked 2021-May-06 at 04:10
            Context

            A truck fleet dispatcher is trying to determine which routes are still accessible after heavy rains flood certain highways. During their trips, trucks must follow linear, ordered paths between 26 waypoints labeled A through Z; in other words, they must traverse waypoints in either standard or reverse alphabetical order.

            The only data the dispatcher can use is the trip logbook, which contains a record of the recent successful trips. The logbook is represented as a list of strings, where each string (corresponding to one entry) has two characters corresponding to the trip origin and destination waypoints respectively.

            If the logbook contains a record of a successful trip between two points, it can be assumed that the full path between those points is accessible. Note that logbook entries imply that both directions of the traversal are valid. For example, an entry of RP means that trucks can move along both R --> Q --> P and P --> Q --> R. Note that the trips A --> B and C -> D do not together imply that B -> C is usable. Entries can have the same character twice, such as C -> C, but this indicates no paths.

            Given an array of logbook entries, the task is to write a function to return the length of the longest consecutive traversal possible; in other words, compute the maximum number of consecutive edges known to be safe. (In even more formal terms, compute the diameter of the largest tree on this graph.)

            I'm trying to return the length of the longest consecutive traversal possible; in other words, computing the maximum number of consecutive edges known to be safe.

            I'm a rookie with Knockout JS and don't know what I am doing wrong.

            I don't think your problem lies with Knockout but with the Bootstrap Tabs. If you look at the CSS classes on each tab, when you click on one of them you'll see active show added to the classes; When you first display the modal (with the tabs) these classes have not been added to Tab 1 so the Bootstrap JS doesn't know that you want it displayed.

            Currently your tabs are set to display on click, which is why clicking on Tab 2 and then clicking on Tab 1 causes it to show.

            There's probably a way to solve this using the Bootstrap Tabs JavaScript but as you've tagged this with knockoutjs then you could force Tab 1 to be displayed by adding those CSS classes yourself - either with a Knockout observable or with vanilla JS.

            No vulnerabilities reported

            Install highway

            This project uses CMake to generate and build. In a Debian-based system you can install it via:.
            You can use the benchmark inside examples/ as a starting point. A quick-reference page briefly lists all operations and their parameters, and the instruction_matrix indicates the number of instructions per operation.
            For up to a power of two N, specify CappedTag<T, N> (or equivalently HWY_CAPPED(T, N)). This is useful for data structures such as a narrow matrix. A loop is still required because vectors may actually have fewer than N lanes.
            For exactly a power of two N lanes, specify FixedTag<T, N>. The largest supported N depends on the target, but is guaranteed to be at least 16/sizeof(T).
            Reside inside namespace hwy { namespace HWY_NAMESPACE {; or
            prefix each op with an alias such as namespace hn = hwy::HWY_NAMESPACE; hn::Add(); or
            add using-declarations for each op used: using hwy::HWY_NAMESPACE::Add;.
            For static dispatch, HWY_TARGET will be the best available target among HWY_BASELINE_TARGETS, i.e. those allowed for use by the compiler (see quick-reference). Functions inside HWY_NAMESPACE can be called using HWY_STATIC_DISPATCH(func)(args) within the same module they are defined in. You can call the function from other modules by wrapping it in a regular function and declaring the regular function in a header.
            For dynamic dispatch, a table of function pointers is generated via the HWY_EXPORT macro that is used by HWY_DYNAMIC_DISPATCH(func)(args) to call the best function pointer for the current CPU's supported targets. A module is automatically compiled for each target in HWY_TARGETS (see quick-reference) if HWY_TARGET_INCLUDE is defined and foreach_target.h is included.
