Introduction To Binary Trees A binary tree is made of nodes, where each node contains a "left" pointer, a "right" pointer, and a data element. The "root" pointer points to the topmost node in the tree. The left and right pointers recursively point to smaller "subtrees" on either side. A null...

To the programmers it is very common concept that bugs are of two types i.e logical errors and syntactic errors. Poor understanding of the problem and solution procedure leads to logical errors whereas, the syntactic errors arise due to poor understanding of the language itself. We can detect these...
