Python算法-双指针(Two Pointers) 双指针分为「对撞指针」、「快慢指针」、「分离双指针」。 参考来源:https://algo.itcharge.cn/ 对撞指针:两个指针方向相反。适合解决查找有序数组中满足某些约束条件的一组元素问题、字符串反转问题。 快慢指针:两个指针方向相同。适合解决数组中的移动、删除元素问题,或者链表中...
I have created an algorithm whose purpose should be of, given two nodes A and B in a BST, it switches the roles (or positions in the tree) of the two by simply moving pointers. In my representation of a BST, I am using a double linked connection (i.e. A.p...

You can find integers from list2 that are in [x - within, x + within] interval for all x from list1 in linear time (O(n)) using "scan line" technique (see How to Find All Overlapping Intervals and Sub O(n^2) algorithm for counting nested intervals?). To en...
If we think similarly as we solved in the two sum problem, what we need to sort the arrays. We started from the beginning of one array and the end of another array. That was our two-pointer algorithm where we traversed the pointers based on the sum of the current...

What ifnums1's size is small compared tonums2's size? Which algorithm is better? What if elements ofnums2are stored on disk, and the memory is limited such that you cannot load all elements into the memory at once? 这道题是之前那道Intersection of Two Arrays的拓展,不同之处在于这道题...
Trie is a fairly standard trie but with bit-level packing so it uses the minimum number of bits to store word indices and pointers. The trie node entries are sorted by word index. Probing is the fastest and uses the most memory. Trie uses the least memory and a bit slower....
TypeError: sse_f() missing 1 required positional argument: 'a_2' And if I use minimize_scalar() I get this error: ValueError: Optimisation bounds must be scalars or array scalars. Any pointers regarding how to fit two alphas or how why I get these errors would be greatly appreciated!
