I can :) just comment lol
Answer:

Explanation:
Considering the number are stored using binary notations.
If there are total 86 bits and 1 bit is used as sign bit. Then in total one can have
bit combinations since a bit can be either stored as 0 or as 1.
Therefore, the largest number that can be stored will be
.
To understand it in better way let's scale down the problem to 3 bits representation. The largest number that can be stored using 3 bits is 111 which in decimal form is 7 and is equal to
.
Explanation:
def letterDigitCount(j):
dic={"digits":0,"letters":0}
for a in j:
if a.isdigit():
dic["digits"]+=1
elif a.isalpha():
dic["letters"]+=1
return dic
