描述

给出三个整数 a, b, c, 如果它们可以构成三角形,返回 true.

• 三角形的定义 (Wikipedia)

样例

给定 a = 2, b = 3, c = 4

返回 true

给定 a = 1, b = 2, c = 3

返回 false

public class Solution {

    /**

     * @param a: a integer represent the length of one edge

     * @param b: a integer represent the length of one edge

     * @param c: a integer represent the length of one edge

     * @return: whether three edges can form a triangle

    public boolean isValidTriangle(int a, int b, int c) {

        // write your code here

        if((a + b) <= c){

            return false;

        }

        if((a+c) <= b){
