The question requires decoding a string containing only numbers. The correspondence between numbers and letters is as follows:
'A' -> "1"
'B' -> "2"
...
'Z' -> "26"
The task is to count how many different ways a string can be decoded. For example, the string "11106"can be decoded as:
"AAJF"(decoded as 1 1 10 6)
"KJF"(decoded as 11 10 6)

Finally, given my background, they asked a few machine learning questions focused on recent work
