I used to take a written test. One of the questions in the test was to calculate the number of times that 1 appeared within 40 billion. At that time, I only gave the idea. The specific implementation was not written. Now I will list the specific implementation code. The following code can only calculate the number less than the N power of 10, instead of the x * 10 ^ N power. To expand the calculation, we al

C language division: Calculate the minimum common divisor of two numbers, and divide the common divisor.
The maximum division of the moving phase is used to calculate the maximum common divisor of two numbers.(A, B) is used to represent the maximum common divisor of a and B.Theorem: We know that a, B, and c are positive integers. If a is divided by B, c (a, B) = (B, c ). (Please refer to other materials for

Analysis and Summary:
When we see the first response to this question, we think it is the reverse order number = |
First use merge sort to calculate the reverse order number AC, which should be the fastest way to calculate the reverse order number, 391 Ms
Then we use a tree array, because each element ranges from 0 to a [I] To 999,999,999, which is too large
The K-largest number in the array can be obtained based on the fast sorting method. The steps are as follows:
1. Randomly select a fulcrum
2. Place the number greater than the pivot point to the left of the array. Place the number smaller than the pivot point to the right of the array. Place the pivot point to the center (left)
3. Set the length of the left part to L,
When K
When K> L, find the number (k-l) in the part recursively
When K = L, returns the Split points (that is, the fulcrum of th
