For example, substrings of string "the" are "" (empty string), "t", "th", "the", "h", "he" … WebMar 7, 2024 · What is the optimal solution to find the sum of substring of a number ? For example, Sum (123) = 1 + 2 + 3 + 12 + 23 + 123 = 164. I think it is O (n^2). because sum = 0 for i in number: // O (n) sum += startwith (i) // O (n) return sum Any optimal solution? What is the best approach? Here is my solution but O (n^2):

WebJul 19, 2024 · Move to c. Substring is abc. It will form 1 pair with itself, so add 3. Sum becomes 5+3 = 8. Copy stack to stack2. At top we have 2. abc and ab will give LCP 2 and they will form 2 pairs. So sum = sum + 2*2. WebMar 9, 2024 · A Computer Science portal for geeks.
