Program Plan Intro

Decryption of the intercepted message

Program plan:

  • Include necessary header files.
  • Declare the namespace.
  • Declare the function “decrypt()”.
  • Define the function “decrypt()”.
    • Declare the necessary variables.
    • Use “for” loop to iterate the string length using the function “strlen()”.
      • Encode the string and assign the result into the variable “Encrypt”.
      • The “if” loop check the condition.
        • True, use the formula to decrypt the message.
      • Otherwise, use the formula to decrypt the message.
      • Assign the decrypted message into the variable “decode[i]”.
  • Define the “main()” function.
    • Declare and initialize the necessary variables.
    • Use “for” loop to iterate the number or key between “1” to “100”.
      • Call the function “decrypt()”.
      • Print the result.
    • Return “0”.

I need help in construct a matlab code to find the voltage, the currents, and the watts based on that circuit.
Objective Implement Bottom-Up Iterative MergeSort and analyze its efficiency compared to recursive MergeSort. Unlike the recursive approach, which involves multiple function calls and stack overhead, the bottom-up version sorts iteratively by merging small subarrays first, reducing recursion depth and improving performance. Task 1. Implement Bottom-Up Iterative MergeSort о Start with single-element subarrays and iteratively merge them into larger sorted sections. Use a loop-based merging process instead of recursion. ○ Implement an efficient in-place merging strategy if possible. 2. Performance Analysis Compare execution time with recursive MergeSort on random, nearly sorted, and reversed datasets. ○ Measure and plot time complexity vs. input size. O Submission Explain why the iterative version reduces function call overhead and when it performs better. • Code implementation with comments. • A short report (1-2 pages) comparing performance. • Graph of execution time vs. input size for…
Given a shared data set, we allow multiple readers to read at the same time, and only one single writer can access the shared data at the same time. In the lecture slides, a solution is given. However, the problem is that the write cannot write forever, if there are always at least one reader. How to ensure that the writer can eventually write? Propose your solution by using semaphores and implemented in Python from threading import Thread, Semaphore from time import sleep from sys import stdout class Reader(Thread): def__init__(self, name): self.n=name; Thread.__init__(self) defrun(self): globalnr, nw, dr, dw whileTrue: # ⟨await nw == 0 then nr += 1⟩ e.acquire() ifnw>0: #if nw > 0 or dw > 0 : dr+=1; e.release(); r.acquire() nr+=1 ifdr>0: dr-=1; r.release() else: e.release() # read data stdout.write(self.n+' reading\n') sleep(1) # ⟨nr -= 1⟩ e.acquire() nr-=1 ifnr==0anddw>0: dw-=1 ; w.release() else: e.release() class Writer(Thread): def__init__(self, name):…
