Solutions to leetcode problems.

Below is the helper functions/aliases used by me to seamlessly fetch new questions, code it in atom, test and submit solution.

    # ask yargs to generate completions.
    type_list=$(../.local/bin/leetcode --get-yargs-completions "${args[@]}")

    COMPREPLY=( $(compgen -W "${type_list}" -- ${cur_word}) )

    # if no match was found, fall back to filename completion
    if [ ${#COMPREPLY[@]} -eq 0 ]; then
