#AdventOfCode #rstats
Day 3 solution
I like my 'stringist' solution for Part 2
# Part 1 str_extract_all(input, "mul\\(\\d+,\\d+\\)") %>% unlist() %>% as.tibble() %>% mutate( first = str_extract(value, "\\d+"), second = str_extract(value, "(\\d+)\\)") ) %>% mutate(across(everything(), parse_number)) %>% mutate(mult = first * second) %>% colSums() # Part 2 clean_input <- gsub("don\\'t\\(\\).*?do\\(\\)", "do\\(\\)", reduce(input, .f = paste0)) # remove patterns between `don't()` and `do()` # then apply part 1 code
