Answer:

Explanation:

The following program is written in Python. It asks the user for the file name (which needs to be in the same directory as the program) and reads the file. It then splits it by lines and saves it into an array. Then it loops through the array, printing each line with its corresponding line number.

file_name = input("File Name: ")

f = open(file_name, 'r')

lines = f.read().split('\n')

for line in lines:

   print(str(lines.index(line) + 1) + ': ' + line)

4) Which is a more efficient way to determine the optimal number of multiplications in a matrix-chain multiplication problem: en
Assoli18 [71]

Answer:

Running RECURSIVE-MATRIX-CHAIN is asymptotically more efficient than enumerating all the ways of parenthesizing the product and computing the number of multiplications of each.

the running time complexity of enumerating all the ways of parenthesizing the product is n*P(n) while in case of RECURSIVE-MATRIX-CHAIN, all the internal nodes are run on all the internal nodes of the tree and it will also create overhead.

lukranit [14]

The BIOS feature that enables a hard drive to read or write several sectors at a time is called IDE block mode

Explanation:

IDE block mode setting speeds up IDE drivers when enabled by allowing multiple sectors to read or write operations. This BIOS feature rushes up hard disk drive passage by transferring many divisions of data per interrupt rather than using the normal single-sector transfer mode.

This mode of transfer is known as block transfers. When block transfers are enabled, depends on the IDE controller, nearly 64 KB of data can be transferred per interrupt.
