Remove K-bit to find minimum numberAn n-bit number, minus the K-bit, how to make the Left (n-k) digits in the original sequence of the number of the smallestFor example8314925 minus 4 numbers, leaving 125 the smallest, note that there is a pre-order requirement, if not the order of course is 123.Solution SolutionsThe greedy algorithm is guaranteed to have an opti

Looking for the largest number of K in programming-like beautySolution One:The problem does not require the smallest number of K ordered, and did not require the final n-k number ordered. In this case, it is not necessary to sort all the elements. At this time, we thought of the choice or exchange sort, namely:1, traversing n

I. Topics and Requirements Given a positive integer in decimal, write down all integers starting with 1, to N, and then count the number of "1" that appears. Requirement: Write a function f (n) to return the number of "1" occurrences between 1 and N. For example F (12) = 5. Within a 32-bit integer range, the maximum n of the "F (n) =n" that satisfies the condition is what.Second

Programming beauty 2.5 find the maximum K number, 2.5 Looking for the maximum number of K in an array, we will first talk about a very simple method, using the segmentation algorithm in quick sorting, that is, we often see the partition. This function returns a value of the int type. This value represents the split point between the first half of the

Prime number refers to the factor is only 1 and its own numbers (1 is not prime), the solution of prime numbers in mathematics is widely used, and the solution of the prime number within N is also our programming often encountered problems, in this problem, the screening method to solve the prime numbers are executed quickly. The following first describes how to infer a is not a prime

The prime number refers to the factor is only 1 and its own numbers (1 is not prime), the solution of prime numbers in mathematics is very extensive, and the solution of the prime number within N is also the problem we often encountered in programming, in this problem, the screening method for solving prime numbers runs very fast. The following first describes how to determine whether a prime

Author: Chen taihan Algorithm-- Find out the number of times the array appears more than halfWhenever I see a classic algorithm question, I miss my high school. I feel that many algorithm questions are the question of high school. Who is my brother? I have read-only specialists, and I have almost never learned a high number of questions.If you have time, you ne

Question 1: Find the number k in N Integers It is similar to the following class fast sorting algorithm, which can be implemented recursively. You need to verify it. Average complexity O (n ). Question 2: Find the maximum number of K in N Integers Two better solutions: O (nlogk) 1. Fast sorting and Recursion Solutio
