R - rangeSum

Question

The code to the problem is not getting resolved: Always gives the error

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

#define the function
rangeSum <- function(a,b){
sum <- 0
for (i in a:b) {
sum <- sum + i
}
return sum
}

result <- rangeSum(x, y)
print(result)

Answer 1

Note that it is
return(sum), not
return sum
