I would like to do some 2-dimensional walks using strings of characters by assigning different values to each character. I was planning to 'pop' the first character of a string, use it, and repeat for the rest of the string.
How can I achieve something like this?
x <- 'hello stackoverflow'
I'd like to be able to do something like this:
a <- x.pop print(a) 'h' print(x) 'ello stackoverflow'
