We need to iterate over all string and use 26**i. Time complexity can be easily reduced to O(n). Space complexity is O(n), which also can be reduced to O(1). But in this problem n is very small: n<=7, so it will not make a lot of difference. class Solution: def titleToNumber (self, s): return sum ([(ord (T)-ord ("A")+ 1)* 26 **i for i,T in enumerate (s[::-1])])

Example A.1.1. Convert the decimal 12345 to base 26. Method 1: Find the highest power of 26 that is less than 12345. 262 = 676 26 2 = 676 and 263 = 17576 26 3 = 17576 so 262 26 2 is the highest power of 26 that is less than 12345. Next, divide 12345 by 676= 262 676 = 26 2 to find a quotient and remainder.
