Question

Calculate the cost of inserting 12 elements in the dynamic array using tight strategy, where the initial array size is 3 and the cost of each operation is 1 unit. Consider the constant "c" used to increase the array size is 3?

Answer #1

Inserting 1st Element = 1

Inserting 2nd Element = 1

Inserting 3rd Element = 1

Increasing size to 6 = 1

Copying the three elements = 3

Inserting 4th Element = 1

Inserting 5th Element = 1

Inserting 6th Element = 1

Increasing size to 9 = 1

Copying the six elements = 6

Inserting 7th Element = 1

Inserting 8th Element = 1

Inserting 9th Element = 1

Increasing size to 12 = 1

Copying the nine elements = 9

Inserting 10th Element = 1

Inserting 11th Element = 1

Inserting 12th Element = 1

Total Cost = 33

Find solutions for each of the linear systems, using
determinants (not Gauss Elimination). You may use a computer
program to perform each determinant operation, but provide each of
the values (?,?,?,?) used to calculate the solution and how they
were obtained. Include a printout documenting your computer
work.
a) −2? + 1? − 4? = −16, 5? + 1? − 3? = −6, 8? + 3? + 1? = 5
b) 5? − ? = 31, 7? − 4?...

JAVA please
Arrays are a very powerful data structure with which you must
become very familiar. Arrays hold more than one object. The objects
must be of the same type. If the array is an integer array then all
the objects in the array must be integers. The object in the array
is associated with an integer index which can be used to locate the
object. The first object of the array has index 0. There are many
problems where...
