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

样例 1:

输入 : a = 2, b = 3, c = 4
输出 : true

样例 2:

输入 : a = 1, b = 2, c = 3
输出 : false

编程语言：Java

解题思想：

1.使用三角形定义。

2.使用条件表达式+if判断。

时间复杂度：O(1)

IDE代码如下：

package LintCode_Easy;
 
public class _765{
 
	public static void main(String[] args) {
		int a = 2, b = 3, c = 4;
		boolean judge;
		if (Math.max(Math.max(a, b), c) == a) 
		{
			judge = (b+c>a)?true:false;
		} 
		else if (Math.max(Math.max(a, b), c) == b) 
		{
			judge = (a+c>b)?true:false;
		} 
		else
		{
			judge = (a+b>c)?true:false;
		}
		System.out.println(judge);
	}
 
}

LintCode编辑器代码如下：

public class Solution {
    public boolean isValidTriangle(int a, int b, int c) {
        boolean judge;
		if (Math.max(Math.max(a, b), c) == a) 
		{
			judge = (b+c>a)?true:false;
		} 
		else if (Math.max(Math.max(a, b), c) == b) 
		{
			judge = (a+c>b)?true:false;
		} 
		else
		{
			judge = (a+b>c)?true:false;
		}
		return judge;
    }
}
