Guys help am given a question on creating a function called rangeSum and adds all the numbers from x to y so l used a for loop

Question

input <- readLines('stdin')
x <- as.integer(input[1])
y <- as.integer(input[2])

#define the function

rangeSum <-function(x,y){
res<-0
for(i in x:y){
res=res+i

}
print(res)
}
This is my code

Answer 1

res <- res + i

and call rangeSum function with input value

rangeSum(x, y)

Answer 2

You cannot use "=" symbol to assign value in R language

You should use <-

So in function there should be

res <- res + i

Now you didn't call that function.

Just creating a function is not enough, you have to call that function to perform operation

As your function accepts two arguments so when you call function you have to pass x and y in that function so that function can accepts argument value

So you should call function after creating function like this:

rangeSum(x, y)

Answer 3

You need to create a function that takes two parameters and returns the sum of all numbers between the two parameters inclusive.
The given code takes two numbers from input and passes them to a function called rangeSum().

Task
Define the rangeSum() function, so that the code works as expected.

Sample Input
4
9

Sample Output
[1] 39

Explanation
For the inputs 4 and 9, the returned value should be 39.
This is the question am lost l didn't understand you
