我们把下面的一条定理称之为Main Theorem: Binary search can be used if and only if for all x in S, p(x) implies p(y) for all y > x. 实际上通过这个属性,我们可以将搜索空间减半,也就是说如果我们的问题的解应用这样的一个验证函数,验证函数的值可以满足上述条件,这样这个问题就可以用二分查找...
二分查找 「二分查找 binary search」是一种基于分治策略的高效搜索算法。它利用数据的有序性,每轮缩小一半搜索范围,直至找到目标元素或搜索区间为空为止 给定一个长度为 (n) 的数组 nums ,元素按从小到大的顺序排列且不重复。请查找并返回元素 target 在该数组中的索引
// Perform binary search on the flattened matrix while left <= right { // Calculate the middle index let mid = left + (right - left) / 2; // Convert the middle index to row and column indices let row = (mid as usize) / n; ...

[file]{binary_search_insertion}-[class]{}-[func]{binary_search_insertion_simple} 存在重复元素的情况 !!! question 在上一题的基础上,规定数组可能包含重复元素,其余不变。 假设数组中存在多个target,则普通二分查找只能返回其中一个target的索引,而无法确定该元素的左边和右边还有多少target。
