Programs to try using vectors - Assignment 5

 Program List

1.Find the largest and second largest element in a vector.

2.Read n numbers and find sum, mean, min, max,median,variance ,standard deviation(use built in fn)

3.Reverse a vector (using rev() and without using rev())

4.Find the frequency of each element in a vector.( use table() , without using table -use unique())

5.Remove duplicate elements(unique and without using unique use %in%)

6.Find the common elements between two vectors.(use intersect() and without using intersect)

7.Read two vectors and find the dot product. ( use sum() and  a user defined function)

8.Replace all negative elemnts with 0 ( use ifelse, use loop)

9.Generate n fibonaci numbers and store in a vector

10.Print the cumulative sum and also print the intermediate sum (use  cumsum() and without using cumsum)

Vector: 10 20 30 40 50 Cumulative Sum: 10 30 60 100 150

11.Find mode ( the most frequent item)

12.Find variance and standard deviation ( use var() and sd() and without using bult-in functions)

13.Seperate  even and odd numbers from a vector into new vectors.

14.Write an R program to read a vector and use a user-defined function to count the number of even and odd elements.

15.Write an R program to read a vector and use a user-defined function to find and return a named vector containg sum, mean, min and max.

Note: 

Students should develop algorithms and implement the programs without relying on built-in functions. Built-in functions may be used only to verify the correctness of the obtained results. These programming assignments are intended to strengthen problem-solving abilities and enhance programming skills in R.
