One, Java side:Define the native method, ' public native long factorial (int n); ', the method is implemented in C + +, computes ' 1 to 20 factorial and ', the argument ' int n ' is the factorial of the first n and (here is 20). Returns the result of the calculation, and return to the Java call.The code is:1 Public classFactorialjava {2 3 Public native Long

the same place:1, syntax similar: because Java can be considered from C + + development, so Java and C language syntax comparison is similar2. Proficiency in programming is the mastery of the Language program library:to some extent, the programming language is composed of syntax and corresponding library,

LeetCode 16 3Sum Closest (C, C ++, Java, Python), leetcode3sumProblem: Given an array S of n integers, find three integers in S such that the sum is closest to a given number, target. return the sum of the three integers. you may assume that each input wowould have exactly one solution. For example, given array S = {-1 2 1 -4}, and target = 1. The sum that

Preface Because of the frequent use of C + +, Java, and C # as a development language in development work, the problem of naming conventions often causes me some trouble. On the one hand, there is no single standard answer to the naming code, on the other hand, although the naming of the language is not a fixed form, the style of three languages is not the same,

Problem:Given a sorted array, remove the duplicates in place such, all element appear only once and return the new L Ength.Do the allocate extra space for another array, and you must does this on place with constant memory.for example,given input Arraynums =[1,1,2] , your function should return length =2 , with the first and elements Ofnums Being1 and2 respectively. It doesn ' t matter what are you leave beyond the new length. Solution: Because it is an ordered array, when the first element

Problem:Given an array S of n integers, find three integers in S such so the sum is closest to a give n number, target. Return the sum of the three integers. You may assume this each input would has exactly one solution. For example, given array S = {-1 2 1-4}, and target = 1. The sum is closest to the target is 2. (-1 + 2 + 1 = 2).Solution: This question and 15 basic similar, even more simple, only need to compare and the result can, encounter and equal to target when you directly return

Problem:Given a sorted array of integers, find the starting and ending position of a Given target value.Your algorithm ' s runtime complexity must is in the order of O(log n).if The target is not a found in the array, Return[-1,-1] . For example,Given [5, 7, 7, 8, 8, 10] and target value 8,Return [3, 4] .Solution: Use binary lookup, then find the beginning and end, returnGiven an array and a target integer, it is required to derive the starting and ending positions of the target integers in the
