LeetCode[17] - Peeking Iterator

再一次理解错题意.peek()就是头顶，但是不一定是最大值啊。总是把PEEK想成了最大值，然后用2STACK做了最大值的cache，练的一手好双stack，可惜错了。回到原题，其实不难。找一个cache来存next()的值，然后每次next()里面维护这个cache就好。/*GivenanIteratorclassinterfacewithmethods:next()andhasNext(),de

oracle中bind peeking问题的解决方法

使用绑定变量可以减少SQL PARSE，但是使用绑定变量有一个不好的地方，就是对于访 问具有倾斜的列，可能使用错误的执行计划。在Oracle 9i之前，如果WHERE 条件里面全 部使用绑定变量，那么只能使用固定的选择性参数来确定执行计划。 =操作和>=操作的选择性为5%，范围扫描的选择性为25%。缺省值的方式可能生成不好的执 行计划。所以Oracle 9i就出现了一个新的技术，bi

*LeetCode-Peeking Iterator

这个classimplementiterator所以不用管是用在什么数据结构上面可以直接使用iterator的nexthasnext因为要peek所以用一个int记录已经peek的值因为peek必定挪动指针可是再next却不能再挪了所以就通过判断这个int是否为null来判断next之前是否peek过了注意peek时也要判断int是否是null连续peek两次应该只挪动一次hasnext也是一样假

bind peeking--绑定变量窥视

绑定变量窥视，就是指oracle在第一次解析SQL语句的时候（也就是说该SQL第一次传入sharedpool），会将你输入的绑定变量的值带入SQL语句里，从而参考你的字面值来猜测该SQL大概会返回多少条记录，从而得到优化的执行计划。然后，以后再次执行相同的SQL语句时，不再考虑你所输入的绑定变量的值，直接取出第一次生成的绑定变量。但是，很可惜的是，使用绑定变量从而共享游标与SQL优化是两个矛盾的目
