In computer science, a jagged array, also known as a ragged array [1] or irregular array [2] is an array of arrays of which the member arrays can be of different lengths, [3] producing rows of jagged edges when visualized as output.
In computer algorithms, block swap algorithms swap two regions of elements of an array.It is simple to swap two non-overlapping regions of an array of equal size. However, it is not simple to swap two non-overlapping regions of an array in-place that are next to each other, but are of unequal sizes (such swapping is equivalent to array rotation).
This change gives the following algorithm (for a zero-based array). -- To shuffle an array a of n elements (indices 0..n-1): for i from n−1 down to 1 do j ← random integer such that 0 ≤ j ≤ i exchange a[j] and a[i] An equivalent version which shuffles the array in the opposite direction (from lowest index to highest) is:

Set a bucket length array to record the length of the unsorted bucket. Initialize into the original array length. [Main Sort] If the bucket length array is cleared and sorted is completed. Execute [Divide function] if it is not cleared. [Divide function] Execute Divide by pop a bucket length from the end of the bucket length array.
The array of Fibonacci numbers is defined where F k+2 = F k+1 + F k, when k ≥ 0, F 1 = 1, and F 0 = 1. To test whether an item is in the list of ordered numbers, follow these steps: Set k = m. If k = 0, stop. There is no match; the item is not in the array. Compare the item against element in F k−1. If the item matches, stop.
Jeffries’ conditions are “irreversible and will continue to worsen over time,” Bieber wrote. “Continued physical and cognitive decline is expected until Mr. Jeffries eventually succumbs to ...
For a fixed length n, the Hamming distance is a metric on the set of the words of length n (also known as a Hamming space), as it fulfills the conditions of non-negativity, symmetry, the Hamming distance of two words is 0 if and only if the two words are identical, and it satisfies the triangle inequality as well: [2] Indeed, if we fix three words a, b and c, then whenever there is a ...
