Week 3: Assignment 3 - Question 1

Due on 2022-03-17, 23:59 IST

Write a C function to find the kth occurrence of an odd integer in a sequence of non-negative integers, and then call your function from main.

Your function should be according to the following declaration:

int find_odd(int k);

Input

You are given the input in two lines:

The first line contains a positive integer k.
In the second line, you will be given a sequence of numbers.

You have to find the kth occurrence of n in the sequence below.

The second line consists of a sequence of non-negative integers,

terminated with a -1. The -1 is not part of the sequence.

Output

If there are k odd numbers in the sequence, then output the kth

occurrence of odd in the sequence. Otherwise, output -1.

Sample Input

1 1 3 2 3 4 1 -1

Sample Output

    while(x!=-1)
    {
          if(x%2!=0)
                ++cnt;
          if(cnt==k)
          { return x;

Week 3: Assignment 3 - Question 2

Due on 2022-03-17, 23:59 IST

In this question, you have to output the "moving average" of a

sequence of non-negative numbers. The moving average is the sequence

of averages of the last 2 entries. For the first number, no average

is output.

For example, if the sequence of numbers is

a1, a2, a3, a4, a5

then the 2-moving average is

(a1+a2)/2, (a2+a3)/2, (a3+a4)/2, (a4+a5)/2

Input

-----

The input is a sequence of non-negative floating point numbers,

terminated by a -1. The -1 is not part of the sequence. There will be

at least 3 numbers in the sequence.

Output

--------------------------------------------------------------------------------------------

You have to output the moving average of the sequence. The output

should be printed correct to one digit after the decimal.

Sample Input 1

-------------------------------------

1 2 3 -1

Sample Output 1

-------------------------

1.5 2.5

Week 3: Assignment 3 - Question 3

Due on 2022-03-17, 23:59 IST

Write a C program to list all the factorial numbers less than or equal

to an input number n.

A number N is called a factorial number if it is the factorial of a

positive integer. For example, the first few factorial numbers are

1, 2, 6, 24, 120, ...

*Note* - We do not list the factorial of 0.

Input

-----

A positive integer, say n.

Output

------

All factorial numbers less than or equal to n.
