Study Notes

Exam 1 Practice Problems

  • Students are strongly advised to attempt practice problems in pencil and paper before verifying in an IDE.
  • Partial credit is applicable to code writing problems, while multiple choice, fill in the blank, true/false questions are autograded.
  • Calculators are prohibited during the exam.
  • Students are also prohibited from using phones, the web, laptops, notes, or electronic media during the exam.

Autograded Style Problems:

  • Problem 1:
    • Code outputs: "The answer is... B True 125"
  • Problem 2:
    • Code outputs: "10 AA"
  • Problem 3:
    • Code outputs: "False True"
  • Problem 4:
    • Code outputs: "Hullabaloo Gig 'em Good Bull Aggies Whoop Howdy"
  • Problem 5:
    • Code outputs: "[9, 16, 25]"
  • Problem 6:
    • Code outputs: "1.0"
  • Problem 7:
    • Code outputs: "The quick brown fox jumped down"
  • Problem 8:
    • Code outputs: "Howdy!Howdy!Welcome to Texas A&M Engineering!Engineering students!"
  • Problem 9:
    • Code outputs:
      • "4 Gig'em Aggies!"
      • "14 Gig'em Aggies!Gig'em Aggies!"
    • Code halts after these two lines due to x becoming a large negative value
  • Problem 10:
    • Code outputs: "0 0"
  • Problem 11:
    • Code outputs: "AB= 2"
  • Problem 12:
    • Code outputs: "2.0"
  • Problem 13:
    • Code outputs: "True"
  • Problem 14:
    • Code outputs: "Green"
  • Problem 15:
    • Code outputs: "B, C, G"
  • Problem 16:
    • Code outputs:
      • "2 A"
      • "4 AA"
    • Code halts after these two lines due to x becoming a large value.
  • Problem 17:
    • Code outputs:
      • "0"
      • "6"
  • Problem 18:
    • Code outputs: "[[[1, 2], [3, 4]], [[5, 6], [7, 8]]]"
  • Problem 19:
    • The code snippet does not include finding the number of digits in the sum of two integers.

Problem 19 - Explanation:

  • The code snippet given in Problem 19 lacks the part to determine the number of digits in the sum, suggesting a missing part.
  • To find the number of digits in the sum:
    • Convert the sum to a string.
    • Find the length of the string.
    • Example Implementation (assuming numSum has been calculated):
      • digitCount = len(str(abs(numSum)))
      • print(digitCount)
      • This code snippet first gets the absolute value of numSum to avoid counting the negative sign before converting it to a string. Then it calculates the length of the string, effectively counting the number of digits.
