fix: lxc resolves to std::lexicographical_compare

[imago]

The snippet lxc should resolve to std::lexicographical_compare and not to std::lexigraphical_compare. This fixes a small typo.

Before:

    if (std::lexigraphical_compare(std::begin(container), std::end(container),
      std::begin(), std::end()) {
      
    }

After:

    if (std::lexicographical_compare(std::begin(container), std::end(container),
      std::begin(), std::end()) {
      
    }
