sum in range

Question

Hi, can I please get some help here?

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().

Answer 1

Use a for loop. The first number being the staring point and the next the condition (e.g. for(int x = starting point; x <= next number; x++)

Then add the numbers together: int sum += x;

Answer 2

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

# function definition
result<-0
rangeSum <- function(x,y){
for(a in x:y){
result<-result+a
}
print(sum(result))
}

rangeSum (x, y)

Answer 3

Thank you both!

Where is your attempts?

Already explanation is given, create a function with 2 parameters and use that parameters in for loop where 1st parameter is a start point and 2nd parameter is end point.

You can do like this:

total = 0

for (x in startPoint : endPoint) {
total = total + x
}

print(total)

Or you can use range function also which is inbuilt function.
