Is it correct or wrong?

Question

input <- readLines('stdin')
x <- as.integer(input[1])
y <- as.integer(input[2])
rangeSum <-function(x,y){
for (i in x:y)
res<-0
res<-i+res
}
Print(res)

Answer 1

Instead don't make function and use loop directly and print res

Answer 2

AML Yakin

No it is wrong you didn't use opening and closings curly brackets on function definition.

You didn't call function and store returned value to print res

rangeSum <- function (x, y) {

#logic
}

result = rangeSum(x, y)
print (result)

Answer 3

You can use the sum method:
sum(startNumber : EndNumber)

Use this command to learn more about the sum() function:

help(sum)

Answer 4

No you still have to use {} and also need to call function

Answer 5

To check if your code is correct, you can copy it and run it on playground – and see if it outputs as expected

Answer 6

Now i do some correction, is it right?
