Given an array of citations (each citation is a non-negative integer) of a researcher, write a function to compute the researcher's h-index. According to the definition of h-index on Wikipedia: "A scientist has index h if h of his/her N papers have a…

Follow up for H-Index: What if the citations array is sorted in ascending order? Could you optimize your algorithm? Hint: Expected runtime complexity is in O(log n) and the input is sorted. 274. H-Index H指数 的拓展.输入的数组是有序的,让我们优化算法.提示(现在题目中没有提示了):O(logn…

oc 与 Swift 是2种不同的语言, oc代码只能写带oc文件里, Swift代码只能写在Swift文件里, 虽然2者不同语言, 但却能互相调用, 不过需要进行一下桥接, 就是下面的2个文件 (ProjectNmae-Bridging-Header.h) Swift文件要调用oc代码的时候 你会发现你无法引用oc.h文件, 所以就要用到这个文件, 对oc文件进行桥接, 把一些oc.h文件在这里引用进去, 然后你就可以在Swift文件里操作oc代码 (ProjectName-Swift.h)…

Money Flow Index 资金流量指数指标 计算: 1.典型价格(TP)=当日最高价.最低价与收盘价的算术平均值 2.货币流量(MF)=典型价格(TP)×N日内成交金额 3.如果当日MF>昨日MF,则将当日的MF值视为正货币流量(PMF) 4.如果当日MF<昨日MF,则将当日的MF值视为负货币流量(NMF) 5.MFI=100-[100/(1+PMF/NMF)] MFI是RSI的扩展,联合效果更好. 观井映天 2015.7.3…
