Question

Def divide(n):

while n>=0 :
m=1/n
n=n−1​
return m

A. When n=1 is the input, on the second iteration of the while loop a division by zero occurs.
B. This algorithm lacks definiteness since division by zero occurs.
C. When n=1 is the input, after the first iteration of the while loop we have m=1 and n=0.
D. When n=1 is the input, the algorithm exits the while loop after the first iteration and outputs m=1.
E. This algorithm works and always outpurs 1. F. This algorithm works and outputs 1/n.

Answer 1

The algorithm uses n as the dividend and n-1 as the divisor. When n=1, after the first iteration of the while loop, m is 1 and n is 0.

Step-by-step explanation:

The algorithm in question performs a division operation using the variable n as the dividend and n-1 as the divisor. The algorithm continues to execute as long as n is greater than or equal to zero.

Option A is incorrect because the algorithm does not cause a division by zero when n=1. Option B is also incorrect because the algorithm does not lack definiteness due to division by zero.

Option C is correct, as when n=1, after the first iteration of the while loop, the value of m is 1 and n is 0. Option D is incorrect because the algorithm does not exit the while loop after the first iteration when n=1. Option E and F are incorrect because the algorithm does not always output 1, and it does not output 1/n.
