  • Буква и символ са две различни неща, по тази причина решението ти за anagrams не е коректно.
  • Помисли си за по-прост начин да изкажеш условието две фрази да са анаграми една на друга.
  • Разгледай внимателно как се чупи примерния тест върху твоето решение.
  • set няма нужда от аргумент, ако е празен
  • Вложените цикли в char_histogram могат да се изразат доста по-приятно с друга конструкция в python, която сме показвали.
