result = arr1[np.triu_indices(2)]: This line overwrites the previous result by using np.triu_indices(2) to generate the indices of the upper triangle of a 2x2 array. These indices are then used to index into ‘arr1’. In this case, the result will contain only the elements in the...

The tectonics of the Afar triple junction is dominated by the motion of three plates: Arabia, Africa (Nubia), and Africa (Somalia). The first rift to open is thought to have been the Gulf of Aden around 30 Ma (Ghebreab1998). Simultaneously, the intense activity of the Afar hotspot (Sc...
有时候做leetcode需要做二叉搜索, 如果不想徒手写的话其实可以用上lower_bound/bisect_left, 真正面试中还可能会写错, 如果没强求徒手写其实也可以用这些api, 如下题: leetcode.com/problems/v 徒手二叉搜索: import bisect class Solution: def triangleNumber(self, nums: List[int]) -> int: nums.sort() ...
