    Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y. The Windows version of Excel supports programming through Microsoft's Visual Basic for Applications (VBA), which is a dialect of Visual Basic .

    So your numbers don't end up with commas at the end. Copy just the number columns to a sandbox or a new section of a page. See relevant sections of Help:Table to do so. In source mode editing use "search and replace" to delete trailing spaces. Check the box for "Treat search string as a regular expression". Replace [ \t]+$ with nothing. Then ...

  4. Data Interchange Format - Wikipedia

    Headers get a 3-line chunk; data, 2. Header chunks start with a text identifier that is all caps, only alphabetic characters, and less than 32 letters. The following line must be a pair of numbers, and the third line must be a quoted string. On the other hand, data chunks start with a number pair and the next line is a quoted string or a keyword.

  5. Separating words problem - Wikipedia

    en.wikipedia.org/wiki/Separating_words_problem

    In theoretical computer science, the separating words problem is the problem of finding the smallest deterministic finite automaton that behaves differently on two given strings, meaning that it accepts one of the two strings and rejects the other string. It is an open problem how large such an automaton must be, in the worst case, as a ...

  6. Spreadsheet - Wikipedia

    Use of named column variables x & y in Microsoft Excel. Formula for y=x 2 resembles Fortran, and Name Manager shows the definitions of x & y. In most implementations, a cell, or group of cells in a column or row, can be "named" enabling the user to refer to those cells by a name rather than by a grid reference.

    Some source data tables only use the codes. Wrap them in brackets {{ABC}} to create full-name country links. To do so click on the wikitext source editing link. Click on "Advanced" in the editing toolbar. Then click on the search and replace icon on the right. Put a check in the box called "Treat search string as a regular expression."

  8. String-searching algorithm - Wikipedia

    en.wikipedia.org/wiki/String-searching_algorithm

    A simple and inefficient way to see where one string occurs inside another is to check at each index, one by one. First, we see if there is a copy of the needle starting at the first character of the haystack; if not, we look to see if there's a copy of the needle starting at the second character of the haystack, and so forth.

  9. Matching wildcards - Wikipedia

    en.wikipedia.org/wiki/Matching_wildcards

    In computer science, an algorithm for matching wildcards (also known as globbing) is useful in comparing text strings that may contain wildcard syntax. [1] Common uses of these algorithms include command-line interfaces, e.g. the Bourne shell [2] or Microsoft Windows command-line [3] or text editor or file manager, as well as the interfaces for some search engines [4] and databases.
