1*39 and 3*13.
Think of the chairs as arrays. The dimensions of the arrays give you the factors of 18.
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.
You have misread or misunderstood something.
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.
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.
Arrays are reported to be omnivoire.
No, but factors can.

for arrays you can list the different arrays and what attributes that you give to them.
