|
<strong>Input:</strong> n = 4
|
|
<strong>Output:</strong> 2
|
|
<strong>Explanation:</strong>
|
|

|
<strong>Input:</strong> n = 3
|
|
<strong>Output:</strong> 3
|
|
<strong>Explanation:</strong>
|
|
At least 3 cuts are needed to divide the circle into 3 equal slices.
|
|
It can be shown that less than 3 cuts cannot result in 3 slices of equal size and shape.
|
|
Also note that the first cut will not divide the circle into distinct parts.
