Professor bunyan thinks he has discovered a remarkable property of binary search trees. suppose that the search for key kk in a binary search tree ends up in a leaf. consider three sets: aa, the keys to the left of the search path; bb, the keys on the search path; and cc, the keys to the right of the search path. professor bunyan claims that any three keys a \in aa∈a, b \in bb∈b, and c \in cc∈c must satisfy a \le b \le ca≤b≤c. give a smallest possible counterexample to the professor's claim.

answer; i do believe that the correct answer is : a deadly factory fire;

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
