Description  0 s, 1 s and ? Marks  Given a string consisting of 0, 1 and ? only, change all the ? to 0/1, so that the size of the largest group is minimized. A group is a substring that contains either all zeros or all ones. Consider the following ex…

UVa和POJ都有这道题. 不同的是UVa要求区分单复数,而POJ不要求. 使用STL做会比較简单,这里纯粹使用指针做了,很麻烦的指针操作,一不小心就错. 调试起来还是很费力的 本题理解起来也是挺费力的,要搞清楚怎样模拟也不easy啊,读题要非常细致. 纯指针的操作挺快的吧. 只是POJ 0ms,而UVa就0.2左右了. 三相链表: 1 仅仅要有叠起来的牌.那么就使用一个down指针指向以下的牌就能够了. 2 使用双向链表,能够方便前后遍历. 3 记得有了更新牌之后.又要又一次開始检查是否须要更…

所谓图像分割指的是根据灰度.颜色.纹理和形状等特征把图像划分成若干互不交迭的区域,并使这些特征在同一区域内呈现出相似性,而在不同区域间呈现出明显的差异性.我们先对目前主要的图像分割方法做个概述,后面再对个别方法做详细的了解和学习. 一.图像分割算法概述 1.基于阈值的分割方法 阈值法的基本思想是基于图像的灰度特征来计算一个或多个灰度阈值,并将图像中每个像素的灰度值与阈值相比较,最后将像素根据比较结果分到合适的类别中.因此,该类方法最为关键的一步就是按照某个准则函数来求解最佳灰度阈值. 2.基于边…
