# There are a few ways in R to read Stdin. The one that works
#   with Hackerrank problems is to open it as a file--
f <- file("stdin")
on.exit(close(f))

# Calling readLines(f) returns a vector of strings, one element 
#   per line of input. You'll have to explicitely convert to int
#   if you're expecting an integer on that line, 
#   or possibly use readr::parse_integer() ?
