Timing circuits are a crucial component of VLSI chips. Here’s a simple model of such a timing circuit. Consider a complete balan
gregori [183]

Answer:

Let L and R be the sub-trees underneath the root r.

If the height of L (where we consider height to be the maximum length of all root-leaf paths) is ∆ more than that of R, ∆ ≥ 0, then the length of the edge  (r, R) is increased by ∆.

Then, we separately perform the same cycle over L and R.

Once more, by induction, argue that this greedy algorithm is efficient –

when it does not increase the length of (r, R) edge by ∆, then prove that the solution can be improved.

Gimme Shelter Roofers maintains a file of past customers, including a customer number, name, address, date of job, and price of
gulaghasi [49]

Answer:

Hence the complete implementation of python code that reads two files and merges them together.

def merge_file(past_file_path,proposed_file_path, merged_file_path):

   past_file_contents=load_file(past_file_path)

   proposed_file_contents=load_file(proposed_file_path)

   proposed_customer_name = []

   for row in proposed_file_contents:

       proposed_customer_name.append(row[1])

   with open(merged_file_path,'w') as outputf:

       outputf.write("Customer Number, Customer Name, Address\r\n")

       for row in proposed_file_contents:

           line = str(row[0]) +", " + str(row[1]) + ", " + str(row[2]) +"\r\n"

           outputf.write(line)

       for row in past_file_contents:

           if row[1] in proposed_customer_name:

               continue

           else:

               line = str(row[0]) + ", " + str(row[1]) + ", " + str(row[2]) + "\r\n"

               outputf.write(line)

       print("Files merged successfully!")

# reads the file and returns the content as 2D lists

def load_file(path):

   file_contents = []

   with open(path, 'r') as pastf:

       for line in pastf:

           cells = line.split(",")

           row = []

           for cell in cells:

               if(cell.lower().strip()=="customer number"):

                   break

               else:

                   row.append(cell.strip())

           if  len(row)>0:

               file_contents.append(row)

   return file_contents

past_file_path="F:\\Past Customer.txt"

proposed_file_path="F:\\Proposed Customer.txt"

merged_file_path="F:\\Merged File.txt"

merge_file(past_file_path,proposed_file_path,merged_file_path)

Your program is going to compare the distinct salaries of two individuals for the last 5 years. If the salary for the two indivi
kirza4 [7]

In python:

i = 1

lst1 = ([])

lst2 = ([])

while i <= 5:

   person1 = int(input("Enter the salary individual 1 got in year {}".format(i)))

   person2 = int(input("Enter the salary individual 1 got in year {}".format(i)))

   lst1.append(person1)

   lst2.append(person2)

   i += 1

if sum(lst1) > sum(lst2):

   print("Individual 1 has the highest salary")

else:

   print("Individual 2 has the highest salary")

This works correctly if the two individuals do not end up with the same salary overall.
