Solution:
An array is an arrangement of a number in the form of rows and columns.
For example ,number
1= 1 × 1
2 = 2 × 1 or 1 × 2
3 = 3 × 1 or 1 × 3
4 = 2 × 2,or 4× 1 or 1 × 4
K= m × n
m =Number of rows, n=Number of columns
First number represent number of rows, and second number represent number of columns.
If in an Array there is only one row and one column, and only single object in that array, we don't need to write anything. We just say that This arrangement contains only one object represented in 1= 1 × 1 array.
