Add two numbers LeetCode Problem
Add two numbers and return the sum assuming the following
- The numbers are non-negative integers or empty.
- The digits are stored in reverse order where each node contains a single digit
Example:
List 1 (l1) = (2,4,3)
List 2 (l2) = (5,6,4)
Expected results = 708 (342 + 465)
Add_Two_Numbers <- function(l1, l2){
x <- as.numeric(paste(rev(l1), collapse = "")) + as.numeric(paste(rev(l2), collapse = ""))
unlist(strsplit(as.character(x), ""))
}
> Add_Two_Numbers(l1 = c(2,4,3),l2 = c(5,6,4))
