libsvm的函数调用方法 详解
本文地址: http://blog.csdn.net/caroline_wendy/article/details/26261173
需要加载(load)SVM的模型, 然后将结点转换为SVM的格式, 即索引(index)+数据(value)的形式;
释放SVM的model有专用的函数: svm_free_and_destroy_model, 否则容易内存泄露;
可以预测数据的概率, 则需...

【题目】
Suppose a sorted array is rotated at some pivot unknown to you beforehand.
(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2).
You are given a target value to search. If found in the array return its index, otherwise return -1.
You may assume no du...

完全按照海涛哥剑指offer里边的递归思路来写的,基本一样,仅作学习验证,努力锻炼,努力学习!code如下:
//Change a BSTree to a sorted double linklist
struct BSTreeNode
{
int value;
BSTreeNode *left;
BSTreeNode *right;
}head;
//Create a node of...

【题目】
Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order.
You may assume no duplicates in the array.
Here are few examples.
[1,3,5,6], 5 → 2
[1,3,5,6]...

信号量和P、V原语由Dijkstra(迪杰斯特拉)提出
信号量
互斥:P、V在同一个进程中
同步:P、V在不同进程中
信号量值含义
S>0:S表示可用资源的个数
S=0:表示无可用资源,无等待进程
S
信号量
struct semaphore
{
int value;
pointer_PCB queue;
}
P原语

【题目】
Given a sorted array of integers, find the starting and ending position of a given target value.
Your algorithm's runtime complexity must be in the order of O(log n).
If the target is not found in the array, return [-1, -1].
For example,
Given [5...
