Suppose an array holds a sequence of N unique numbers that are sorted in decreasing order. If we move the last P numbers (P<N) to the beginning of this sequence of numbers, then what is the best possible Big-O time complexity you can achieve to search for a specific given number? For example, suppose we have the following sequence of numbers: {10,9,8,7,6,5,4,3,2,1} Suppose P were 4 and someone moved the last P numbers to the beginning: 4,3,2,1,10,9,8,7,6,5} If we don't know P and want to search for a number (say, 7), what is the most efficient algorithm then?
