What is the output of the given pseudocode? a = 8; b = 43; if a * b < 10 -> Level 1; elseif a - b < 20 -> Level 2; elseif a - b > 30 -> Level 3; else -> Level 4. What is the output?

Rationale

Level 2

The pseudocode evaluates conditions in sequence, and the first condition that evaluates to true determines the output. In this case, the calculation of `a - b` results in a negative value, which satisfies the second condition, leading to the output "Level 2."

A (Level 1) YOUR ANSWER

This output would occur if the product of `a` and `b` was less than 10. However, since `a = 8` and `b = 43`, their product is 344, which is significantly greater than 10. Therefore, this condition is false.

B (Level 2) CORRECT

This output is produced when `a - b < 20`. Given `a = 8` and `b = 43`, the calculation results in `8 - 43 = -35`, which is indeed less than 20. Thus, this condition is true, and the output is "Level 2."

C (Level 3) YOUR ANSWER

This output would be the result if `a - b > 30`. The difference `8 - 43` is -35, which does not satisfy this condition. As such, this option is incorrect.

D (Level 4) YOUR ANSWER

This output is associated with the scenario where none of the previous conditions are true, leading to the default case. However, since the condition for "Level 2" is satisfied, this case does not apply here.

Conclusion

The pseudocode evaluates several conditions based on arithmetic operations. Among the given options, only "Level 2" correctly reflects the outcome of the calculated difference `a - b`. The first true condition stops further evaluation, confirming that "Level 2" is the output of the pseudocode.

What is the output of the given pseudocode? a = 8; b = 43; if a * b < 10 -> Level 1; elseif a - b < 20 -> Level 2; elseif a - b > 30 -> Level 3; else -> Level 4. What is the output?

Level 2
