We do not know how the threads will be scheduled in the operating system, even though the numbers in the input seems to imply the ordering. The input format you see is mainly to ensure our tests’ comprehensiveness.题目大意现在三个线程,每个线程分别调用三个函数中的一个。无论线程的产生和调用...
In mathematics, the Fibonacci numbers or Fibonacci series or Fibonacci sequence are the numbers in the following integer sequence: By definition, the
2. Create a vector of Fibonacci numbers and print them using the function from exercise 1. To create the vector, write a function, fibonacci(x,y,v, n), where integers x and y are ints, v is an empty vector, and n is the number of elements to put into v; v[0] will be x ...

There are another kind of Fibonacci numbers:F(0) = 7,F(1) = 11,F(n) = F(n-1) + F(n-2) (n>=2) InputInput consists of a sequence of lines,each containing an integer n.(n < 1,000,000)OutputPrint the word "yes" if 3 divide evenly into F(n).Print the word
