Index numbers are important in economic statistics. 1) Explain what an index number is. If we look at the for loop in update() operation, we can see that the loop runs at most the number of bits in index x which is restricted to be less or equal to n (the size of the given array), so we can say that the update operation takes at most O(log2(n)) time. Relative method: The price of each item in the current year is expressed as a percentage of price in base year. A rising general price level over time is a pointer towards inflation, while a falling general price level over time is a pointer towards deflation. Binary-indexed-tree.
