export GO111MODULE="on"

Now fetch dependent modules and build the executable

go mod tidy && go build -o set-intersection-exercise main.go

To Run

./set-intersection-exercise --first-file=[path_to_first_file]] --second-file=[oath_to_second_file] --key=foo

Output

Count of keys ([path_to_first_file]]):           [no. of keys]
Count of distinct keys ([path_to_first_file]):   [no. of distinct keys]
Count of keys ([path_to_second_file]):           [no. of keys]
Count of distinct keys ([path_to_second_file]):  [no. of distinct keys]
Total overlapping keys:                          [total overlapping keys]
Distinct overlapping keys:                       [total distinct keys]
