After a lot of practice in LeetCode, I've made a powerful binary search template and solved many Hard problems by just slightly twisting this template. I'll share the template with you guys in this post.I don't want to just show off the code and leave. Most importantly, I want to s...
} leetcode中最快的方法是调用STL中的lower_bound函数 template <classForwardIterator,classT>ForwardIteratorlower_bound(ForwardIterator first, ForwardIterator last,constT& val); lower_bound在[first,last)的左闭右开区间寻找第一个不小于val的元素,采用了二分查找的思想 Returns an iterator pointing to the ...
Binary Search思考和写代码的重点是n=2的时候细节怎么处理,这一点至关重要。另一种写法 int find(vector<int>& nums, int target) { int low = 0, high = nums.size()-1; while (low <= high) { int mid = low + (high-low) / 2; if (nums[mid] == target) return mid; else if (nums...

另外,Binary Search并不是只能适用于「给定一个数组,搜索一个目标数字」这样简单的场合,它有着更为一般化的应用场景。 我会在这篇文章里详细地总结这些内容,并把它应用到LeetCode的实际题目中。我不希望只是简单地贴出每道题目的代码,我所希望分享的是思路,是如何将最一般化的Binary Search模板应用到各种题目上面,...
