Lintcode——765. Valid Triangle

判断三角形

三角形两边和大于第三边，两边差小于第三边

代码：

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 && a+c>b && b+c>a){
            return true;
        }
        return false;
    }
}
