Please help me fix my code!!!! Thanks
Unable to build program BUILD OUTPUT IntTreeTest.java:14: error: method evenBranches in class IntTree cannot be applied to given types; assertEquals(new GoodIntTree(s).evenBranches(), new IntTree(s).evenBranches()); required: IntTreeNode found: no arguments reason: actual and formal argument lists differ in length IntTreeTest.java:30: error: method evenBranches in class IntTree cannot be applied to given types; assertEquals(new GoodIntTree(s).evenBranches(), new IntTree(s).evenBranches(); A required: IntTreeNode found: no arguments reason: actual and formal argument lists differ in length 2 errors
