Teaching Kids Programming: Videos on Data Structures and Algorithms Example: Find the integer cubic root of a^3=54872 First of all, we need to find out how many digits of a, which is easy to find out. “a” is a 2-digit number since 54872 is between 10^3 and 100^3. Also, the digit at One is 8, because 8^3 ends 2 and all other digits to the power of 3 don’t end at 2. So we can bruteforce the digit at ten, which only gives 9 choices: ans = -1 for i in range(1, 10): num = (i * 10 + 8)**3 Continue Reading »
