Question
**Algorithm #1 - Direct Sum**

**Objective:** Compute the sum of integers from 0 to N-1.

```plaintext
sum = 0

for i in range(0, N):
    sum += i

print("sum =", sum)
```

**Explanation:**
The algorithm initializes a variable `sum` with 0 and iterates through a loop, where it adds each integer `i` from 0 to N-1 to `sum`. Finally, it prints the total sum. This simple algorithm demonstrates a fundamental approach to aggregating a sequence of numbers.
