Web@Baso Yes, log (N) as the number of digits is base 10. Note however that O (log_10 (N)) is equivalent to O (log_2 (N)) because changing the base of the logarithm is just a constant multiplicative factor. Hence, for discussing Big-O notation, generally the base of the logarithm is omitted as it doesn't matter. – k_ssb Jan 26, 2024 at 3:50
