A non-empty zero-indexed array A consisting of N integers is given. A pair of integers (P, Q), such that 0 ≤ P < Q < N, is called a slice of array A (notice that the slice contains at least two elements). The average of a slice (P, Q) is the sum of A[P] + A[P +...

【LeetCode】 Longest Common Prefix 【Python || C++】 题目: 最长的前缀公共子字符串 Write a function to find the longest common prefix string amongst an array of strings. If there is no common prefix, return an empty string "". Example 1: Example 2: &nb......
Write a function to find the longest common prefix string amongst an array of strings. 分析: 对一组字符串找到最长公共前缀。 因为只是找前缀所以可以以第一个字符串为基础,按个字符与其它字符串比较,直到有字符串已经遍历完或者碰到不一致的字符,返回到当前为止第一个字符串的前缀即可。
The code to solve the Java prefix sum problem with the Vector API is as follows: intarray[] = { 10, 20, 12, 28, 10, 19, 101, 799 };varvector = IntVector.fromArray(IntVector.SPECIES_PREFERRED, array, 0);System.out.println(vector);vector = vector.add(vec...
