因为所在学校是大摩的Target School,所以相对比较容易得到面试。大摩只来我校招IT。面试官系一位老印，很Smart,面试过程中被我夸了好几句。足见，我的表现是…废话少说，亮题。
数学+程序的面试
Question 1:
In a deck of 52 card, what is the probability to have a hand of 13 cards that are from the same suit?
My solution:
4 52
/
1 13
Your solution:52*12!/ 52!
/* 很显然，对于简单的题目，面试官Expect你回答出多种方法，而不仅仅是答案正确。 */
Question 2:
Cut one stick twice to turn it to be three sticks, what is the probability that the three sticks form a triangle?
My solution:
Set the length of the original stick to be l, the length of the first segment to be x, the length of the second segment to be y, then the length of the third segment becomes （l-x-y）。
There are three constraints based on the rule “the sum of two edges of a triangle is greater than the length of the third edge.” I set up three inequalities.
The problem of my solution: Cannot obtain the final result within 5 minutes.
Your solution: （1/ 2）*（1/ 2）
/* 脑筋急转弯。不能从传统的数学方法求解，因为时间根本不够的 */
Question 3:
I was given 100 integers listing from 1 to 100 without order. Then, an arbitrary value from this list is missing. How to find which value it is?
/* 这可不是编程题哦，可我当时就是当编程题给他做了。Sigh,好在是做对了。*/
