Namely, instead of working with individual digits, implement multiplication in base 100000. Then at the end, total the digits within each super-digit. I don't know how good a computer you were allowed in the contest, but I have a desktop at home that is roughly as old as the contest....
Use modulus operator (%) to compute the last digit. Generalise modulus operator idea to compute all digits. leetcode-debugger To get the digits of a integer, we can iteratedly divide the integer by ten, and retrieve the right-most digit by using modulous operator (%). The time complexity...
Find the total sum of all root-to-leaf numbers. Note:A leaf is a node with no children. Example: Input: [1,2,3] 1 / \ 2 3 Output: 25 Explanation: The root-to-leaf path 1->2 represents the number 12. The root-to-leaf path 1->3 represents the number 13. ...
