  • char_histogram и group_by_type можеш да я подобриш, ако си прегледаш хитринките
  • сортировката не ти е стабилна, а по условие се иска да е такава (ако не знаеш какво е това питай тук)
  • забележи, че функцията се казва anagrams, а не anagram
  • при анаграмите - трябва да гледаш само буквите и то без значени дали са главни или малки
  • в Python се swap-ва така a, b = b, a
