Look at most sorted list of filenames, product names, or any other text that contains alphanumeric characters - both letters and numbers. Traditional sorting algorithms use ASCII comparisons to sort these items, which means the end-user sees an unfortunately ordered list that does not consider the numeric values within the strings.
For example, in a sorted list of files, "z100.html" is sorted before "z2.html". But obviously, 2 comes before 100!
