As seen in the image , the evaluation of the same test case after RU and after SUBMIT are different.
I have encountered with this problem many times.

I dont see any trouble in my code:

class A{
boolean found=false;
}
class Solution {
private void f(TreeNode root,int currentsum, int targetsum,A a){
if (a.found) return;
if (root==null){
if (currentsum==targetsum){
a.found=true;
}
return;
}

    currentsum=currentsum+root.val;
    f(root.left,currentsum,targetsum,a);
    f(root.right,currentsum,targetsum,a);
    
}

public boolean hasPathSum(TreeNode root, int targetSum) {
    if (root==null) return false;
    if (root.val==targetSum) return true;
    A a=new A();
    int currentsum=0;
    f(root,currentsum,targetSum,a);
    return a.found;
    
}

}
