Хм, интересное задание.
Кол-во символов в строке = 24
Кол-во букв "a" на английской раскладке = 8
Кол-во букв "s" = 8
Кол-во букв "d" = 8
"a" = "s" = "d"
"a" + "a" = 16
"a" + "s" = "s" + "a" = 16
"a" + "d" = "d" + "a" = 16
"s" + "s" = 16
"s" + "d" = "d" + "s" = 16
"d" + "d" = 16
"a" - "a" = 0
"a" - "s" = "s" - "a" = 0
"a" - "d" = "d" - "a" = 0
"s" - "s" = 0
"s" - "d" = "d" - "s" = 0
"d" - "d" = 0
"a" : "a" = 1
"a" : "s" = "s" : "a" = 1
"a" : "d" = "d" : "a" = 1
"s" : "s" = 1
"s" : "d" = "d" : "s" = 1
"d" : "d" = 1
"a" × "a" = 64
"a" × "s" = "s" × "a" = 64
"a" × "d" = "d" × "a" = 64
"s" × "s" = 64
"s" × "d" = "d" × "s" = 64
"d" × "d" = 64
