What is a binary search ?

The binary search tree is a sophisticated algorithm for analysing nodes, their left and right branches, which are represented in a tree structure, and returning the value. The BST is built on the architecture of a basic binary search algorithm, allowing for faster node lookups, insertions, and removals. As a result, the program is extremely fast and accurate.

The main reason is if the array index first is greater than the array index of the last position at this point the search stops and gives the wanted result

Hence to conclude the binary search stops after looking the item if the array index first is greater than the array index last

The internal fragmentation after all programs are loaded into memory is 13420.

Internal fragmentation is something that occur if memory is have fixed-sized blocks distributed. It means the memory allocated to process is larger than the demanded memory, the different is called internal fragmentation.

To calculate the scope of internal fragmentation we simplified only sum all mod from demanded memory by the multiply system RAM and system uses memory. So,

First is,

1 MB RAM * 4 kB = 1024 * 4 = 4096

Then,

4096 - (167852 % 4096) = 84

4096 - (209376 % 4096) = 3616

4096 - (32866 % 4096) = 3998

4096 - (254871 % 4096) = 3177

4096 - (128527 % 4096) = 2545

Next,

84 + 3616 + 3998 + 3177 + 2545

= 13420.

Thus, the scope of internal frag is 13420.

The most suitable deployment configuration to satisfy this requirement would be a Blue/Green deployment strategy.

What is deployment?
All of the procedures that make a software system usable collectively constitute software deployment. There may be transitions between the various activities that make up the general deployment process. These actions may take place on either the consumer or producer side, or even on both. The specific processes as well as procedures inside every activity are difficult to defined since every software system is different. In light of this, "deployment" should be understood as a general procedure that needs to be tailored to meet particular requirements or characteristics.

Blue/Green deployments involve deploying two identical versions of a system side-by-side, but only one of the systems is live and accessible to users at a given time. This allows for a gradual, incremental shift in traffic from the original system (the "blue" version) to the new system (the "green" version). In this case, the first increment of 10% traffic can be routed to the green version, and the remaining 90% can be routed to the green version five minutes later. This ensures that the new version is gradually tested, reducing the risk of any unexpected errors.

a ) From the above algorithm, it is clear that insertion sort can cause the complexity of the solution to be O(n2) since its worst-case complexity is O(n2) when elements are not distributed uniformly. This occurs when a bucket is filled with all the elements and an insertion sort is applied to it.

Insertion sort is a sorting algorithm that, after each iteration, places an unsorted element in the appropriate location. Insertion sort functions similarly to how we sort the cards in our hand in a card game.

Since we know the first card is already sorted, we choose an unsorted card. The unsorted card is positioned to the right if it is larger than the card being held in the hand; if not, it is positioned to the left. Other unsorted cards are taken and placed in their proper positions in a similar manner. Insertion sort follows a similar strategy.

b) We use bucket sort because we assume that the data is uniformly distributed over a range; each bucket has a small number of elements, and some may be partially sorted. Insertion sort can sort a small number of elements quickly, taking an average of O(m) time for each m element bucket. Mergesort and quicksort have O(mlogm) complexity, so they should be avoided.

So, use modulo (%) to determine how many images would be left over if you divided the images into rows of 4.

What is a modulo (%) operator?

When two integers are divided, the math operation modulo determines the remainder. It is commonly written as mod or symbolized with the symbol %.

A mod b = r,  for two integers a and b.

When an is the dividend, b is the divisor (or modulus), and r is the leftover, the equation is as follows.

Examples

11 mod 4 Equals 3 since 11 divides by 4 twice, leaving 3 in the result.

25 divided by 5 (five times) results in 0 remainder, therefore 25 mod 5 = 0.

Since 3 divides by 2 (once), leaving 1 remaining, 3 mod 2 =1.

All odd numbers provide a leftover of 1 when divided by 2, hence 5 mod 2 = 1.
