print(np.unique(x)): The np.unique function returns the sorted unique elements of the input array x. In this case, the unique elements are 10, 20, and 30, so the output will be [10 20 30]. x = np.array([[ 1, 1], [2, 3]]): Creates a 2x2 NumPy array with elements 1, ...
* erase uses a vector operation to remove the nonunique elements*/vector<string>::iterator end_unique = unique(words.begin(), words.end());words.erase(end_unique, words.end());在STL中unique函数是一个去重函数， unique的功能是去除相邻的重复元素(只保留一个),其实它并不真正把重复...
