The number of arrays (or subsets) that can be formed from a set of 42 elements is determined by the formula (2^n), where (n) is the number of elements in the set. Therefore, for 42 elements, the number of possible arrays is (2^{42}), which equals 4,398,046,511,104. This includes all possible combinations, including the empty set and the full set itself.
The rectangular arrays for the number 12 consist of all the pairs of factors that multiply to give 12. These arrays are: 1x12, 2x6, 3x4, and 4x3. Each pair represents a different arrangement of rows and columns, resulting in a total of four distinct rectangular arrays for the number 12.
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.
All integers that are not perfect squares.

4 (or eight if you count transposed arrays as being different).
If you answer 42x42,the answer is1 764 arrays.
Not counting rotations, there are 4.
One efficient way to find the median of k sorted arrays is to merge all the arrays into one sorted array and then find the middle element. This method has a time complexity of O(n log k), where n is the total number of elements in all arrays and k is the number of arrays.

I assume you mean that you have a number of rows, and that not all rows have the same number of "cells". Yes, in Java a two-dimensional array is implemented as an array of arrays (each item in the top-level array is, in itself, an array); a 3-dimensional array is an array of arrays of arrays, etc.; and there is no rule stating that all secondary (etc.) arrays must have the same number of elements.
const int n = 100; // fixed-length arrays have a constant length int x[n]; // a fixed-length array of 100 integer elements (uninitialised) for (int i=0; i<n; ++i) x[i] = 42; // Assign value 42 to all elements of x using i as the indexer:
The median of two sorted arrays is the middle value when all the numbers are combined and arranged in ascending order.
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
