  2. Merge (version control) - Wikipedia

    en.wikipedia.org/wiki/Merge_(version_control)

    Manual merging is also required when automatic merging runs into a change conflict; for instance, very few automatic merge tools can merge two changes to the same line of code (say, one that changes a function name, and another that adds a comment). In these cases, revision control systems resort to the user to specify the intended merge result.

    In computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory. For example, in a program, two variables may be defined thus (in pseudocode): data_item x := 1 data_item y := 0 swap (x, y);

  9. Block sort - Wikipedia

    en.wikipedia.org/wiki/Block_Sort

    Rather than merging A and B directly as with traditional methods, a block-based merge algorithm divides A into discrete blocks of size √ A (resulting in √ A number of blocks as well), [2] inserts each A block into B such that the first value of each A block is less than or equal (≤) to the B value immediately after it, then locally merges ...
