Question

What is the value of j at the end of the following code segment?
j = 0
for i in range(0, 4) :
   j = j + i

BlackTom AI · Accepted Answer

The code initializes j to 0 and then iterates i over the values produced by range(0, 4).
During each iteration, j is updated by adding the current i value to it.
Step through each loop: when i = 0, j becomes 0 + 0 = 0; when i = 1, j becomes 0 + 1 = 1; when i = 2, j becomes 1 + 2 = 3; when i = 3, j becomes 3 + 3 = 6.
Thus, after the final iteration, j holds the value 6.
Now evaluate the answer options:
- Option "10": This would imply summing a different sequence or miscounting iterations; it does not match the actual total of 0+1+2+3.
- Option "8": This could come from summing only 0+1+2 or misapplying the range bounds; it ignores one of the terms or double-counts, which isn’t what the loop does.
- Option "6": This equals the correct total of 0+1+2+3 accumulated through the four iterations, matching the actual execution.
- Option "4": This might reflect counting only the first two terms (0+1) or stopping early, which isn’t what the loop does here.
By tracing the loop step by step and totaling the i values as they are added to j, the correct total corresponds to the sum of 0 through 3, which is 6.
