Microsoft Interview Question – Get the Area of the Triangle 微软面试题:三...

The following seems an easy question, to get the area of the rectangluar triangle with the slope equals to 10 and the height equals to 6.

据说是一个印度人杀入微软最后的面试, 面试官给了这么一道小学数学几何题:

If your answer is 30 (10×6/2), then you are falling into the trap: Such triangle doesn’t exist at all!

这哥门也有疑问可是最后还是坚持答案 30 (底 X 高 / 2)

这是个陷井: 这个直角三角形是不存在的. If we label the triangle with the following,

两个小直角三角形的勾股定理: What we can get are:

两者相加: If we add these two equations:

简化一下: After simplification, we have:

最后我们得到: Thus

因为

如果并且把函数画出来是这样的

If and the function of is plotted below.

最大值是 25 也就是说 c 的最大值是 5 所以这样的三角形是不存在的(斜高是6)

The maximum value for function y is 25, which means that the maximum value of c is 5.

Such triangle does not exist (the height is 6, which exceeds the maximum length)!

这个问题的意义在于,在实际工作中,尤其是面对开放性,创造性的工作时,不能仅仅作为一个执行者,要怎么做,我也不知道

Typical Microsoft. If something is wrong then it is by design…and you are stuck with it.
