Explanation:
1️⃣ Variable Initialization
x = 1
A variable x is created.
Its initial value is 1.
This value will be updated repeatedly inside the loop.
2️⃣ Loop Declaration
for i in range(1, 6):
This loop runs with i taking values:
1, 2, 3, 4, 5
The loop will execute 5 times.
3️⃣ Loop Body (Core Logic)
x *= i - x
This line is equivalent to:
x = x * (i - x)
Each iteration:
First computes (i - x)
Then multiplies the current value of x with that result
Stores the new value back into x
4️⃣ Iteration-by-Iteration Execution
🔹 Iteration 1 (i = 1)
Current x = 1
Calculation:
x = 1 × (1 − 1) = 0
Updated x = 0
🔹 Iteration 2 (i = 2)
Current x = 0
Calculation:
x = 0 × (2 − 0) = 0
Updated x = 0
🔹 Iteration 3 (i = 3)
Current x = 0
Calculation:
x = 0 × (3 − 0) = 0
Updated x = 0
🔹 Iteration 4 (i = 4)
Current x = 0
Calculation:
x = 0 × (4 − 0) = 0
Updated x = 0
🔹 Iteration 5 (i = 5)
Current x = 0
Calculation:
x = 0 × (5 − 0) = 0
Updated x = 0
5️⃣ Final Output
print(x)
After the loop ends, x is still 0.
So the output printed is:
0
