Given an integer arraynums, return the number of range sums that lie in[lower, upper]inclusive. Range sumS(i, j)is defined as the sum of the elements innumsbetween indicesiandj(i≤j), inclusive. Note: A naive algorithm ofO(n2) is trivial. You MUST do better than that. Example: Give...
Given a set of digits S, and an integer n, you have to find how many n-digit integers are there, which contain digits that belong to S and the difference between any two adjacent digits is not more than two. Input Input starts with an integer T (≤ 300), denoting the number of te...
