The number of factorial end 0 of N and the position of the last bit 1 in the binary representation

line, if the result is 8, then 8 is 2 3 power, that is 8 of the last 1 in the bottom 4th.So how to count n! How many powers is 2? Of course, we only have to count when the multiplication from a few 2 multiplied on it, or the first problem as the decomposition factor multiplied ah, see the total number of factors in 2

PHP dynamic planning solution for 0-1 knapsack problem instance analysis

PHP dynamic planning solution for 0-1 knapsack problem instance analysis This article mainly introduces PHP dynamic planning to solve the 0-1 knapsack problem.

1.问题描述   给定n种物品和一个背包,物品i的重量是wi,其价值为vi,背包的容量为C。问:应该如何选择装入背包的物品,使得装入背包中物品的总价值最大? 2.问题分析   上述问题可以抽象为一个整数规划问题,即求满足 (a)Σwixi≤ C;(b)xi ∈(0,1), 1≤i≤n;条件下,∑vixi最大时的一个物品xi序列。分析问题可以发现,该问题具有最优子结构性质,那么就可以尝试用动态规划方法求解,而动态规划求解的关键就是列出问题的递归关系表达式。   设m(i,j)为背包容量为j,可选物品为i,i+1,...n时0-1背包问题的最优质,

"Backpack" 0-1 backpack with full backpack one-dimensional array implementation

Backpack problem is very classic, "backpack problem Nine" speak very detailed, suggest to take a look. Here, I want to give 0-1 backpacks and complete backpack compression space after the implementation, that is, as long as a one-dimensional array. The 0-1 backpack, unlike the complete backpack, is just the same as

the maximum value. If you do not place 1 item, the remaining backpack capacity is 2, the maximum value available for the remaining backpack capacity is 3, so the best time should be put into item 1; when the backpack capacity is 3, if put 1 item, get value 6, the maximum value available for the remaining backpack capacity 1

people. Transfer it by the way to record where it is transferred from the value, to facilitate the final output. In this way, it is possible to do so as long as the number of gods or the number of demons in the final processing of all collections is exactly the case. Follow the recorded transfer traverse back to output all the solutions on the line. Adding a small optimization is that when the two quantities of a set are equal, they can be judged directly, because the two numbers are equivalent

How many times has the 0~400 1 appeared?

It's a little piece of cake in the neighborhood today: "How many times did 1 appear in 0~400?" ”。Side dishes to see the majority of users to the algorithm is based on string processing, the idea is roughly: stitching all the numbers into a string, and then processing the string, and then get the number of occurrences. For example, the following code:1 /**2 * User
