Logic, algorithms and problem solving

Give the line number where selection is used in the program in 12(a).

State the output of the program in 12(a).

Explain the purpose of the loop on line 3 of the program in 12(a).

This program checks a password.

1  password = input("Enter password: ")2  attempts = 13  while password != "Plasmo7" and attempts < 3:4      password = input("Try again: ")5      attempts = attempts + 16  if password == "Plasmo7":7      print("Access granted")8  else:9      print("Locked out")

State the line number where iteration begins.

A user enters `abc`, then `123`, then `xyz`. State the output of the program in 12(a) and the final value of `attempts`.

Explain why the keyword `and` is used on line 3.

Using line numbers from the program, explain the difference between sequence and selection.

What is an algorithm?

An agent must find a route through this grid from S to E. It can move Up, Down, Left or Right one square at a time. # is a wall.

     col1 col2 col3 col4row1  S    .    .    #row2  #    #    .    #row3  .    .    .    .row4  #    E    #    .

Write the shortest sequence of moves from S to E.

State the number of moves in the shortest route in 12(a).

def classify_temp(t):    if t < 10:        return "cold"    elif t < 25:        return "mild"    else:        return "hot" readings = [8, 25, 17]for r in readings:    print(classify_temp(r))

State the output of this program.

Which logical structure is used when a program chooses between two different paths?

temps = [14, 18, 21, 19, 25]total = 0for t in temps:    total = total + taverage = total / len(temps)print(average)

State the output of this program.

Identify the iteration construct in the program in 13(a) and describe what it does.

What is decomposition?

names = ["Ana", "Ben", "Cal"]scores = [72, 58, 91]for i in range(len(names)):    if scores[i] >= 60:        print(names[i], "pass")    else:        print(names[i], "retake")

State the output of this program.

Which expression is True only when `a` is greater than 5 and `b` is less than 3?

def count_vowels(word):    count = 0    for letter in word.lower():        if letter in "aeiou":            count = count + 1    return count print(count_vowels("Robot"))

State the output of this program.
