+### Example 1:
+- Input: `numCourses = 2, prerequisites = [[1,0]]`
+- Output: `true`
+- Explanation: There are a total of `2` courses to take. To take course `1` you should have finished course `0`. So it is possible.
+
+### Example 2:
+- Input: `numCourses = 2, prerequisites = [[1,0],[0,1]]`
+- Output: `false`
+- Explanation: There are a total of `2` courses to take. To take course `1` you should have finished course `0`, and to take course `0` you should also have finished course `1`. So it is impossible.
+
+### Constraints:
+
+- `1 <= numCourses <= 2000`
+- `0 <= prerequisites.length <= 5000`
+- `prerequisites[i].length == 2`
+- `0 <= ai, bi < numCourses`
+- All the pairs `prerequisites[i]` are unique.
+
+## Solution
+
+```py
+class Solution:
+    def canFinish(self, numCourses: int, prerequisites: list[list[int]]) -> bool:
+```
