proportional to the square of N. When N doubles, the running time increases by N * N.
while(low <= high) { mid = (low + high) / 2; if (target < list[mid]) high = mid - 1; else if (target > list[mid]) low = mid + 1; else break; }
This is an algorithm to break a set of numbers into halves, to search a particular field(we will study this in detail later). Now, this algorithm will have a Logarithmic Time Complexity. The running time of the algorithm is proportional to the number of times N can be divided by 2(N is high-low here). This is because the algorithm divides the working area in half with each iteration.
