Can't find error in this problem

can any one tell why my can finish funciton is giving false for the "course schedule " 1 problem?
i added various cout statements to debug it but still can’t find the error.
My approach is if the graph is a dag, then we will have a topological sort which will mean that we can complete the courses.

Code:

class Solution {

    bool checkCycle(vector<vector<int>> &graph,vector<bool> &visited,vector<bool> &dfsVisited,int src)

        visited[src]=true;
        dfsVisited[src]=true;
        for(auto it : graph[src])
        {
            if(!visited[it]){
                 if(checkCycle(graph,visited,dfsVisited,it))
                 {

Hey @abhinav_700
Thanks for sharing your doubt.

you add a semicolon at the end of the if statement. Just remove it, and your code will run properly.

thanks alot
