Hello I am trying to solve these problems and I am not allowed to use loops or 
ifs.

1st Question
My first question is that I have generated 100 random numbers from the uniform 
distribution then 
A)add only the negative integers. 
B)add elements until the first appearance of a negative element. 

I know how to choose the negative elements for A but how to find integers? 
And I dont know what to do for B.

2nd Question
 Simulate 1000 observations from the student-t distribution with 3 degrees of 
freedom and then calculate the truncated mean by excluding bottom 5% and top 5%.

Thank yoou
