Given a number ‘n’, find the smallest number ‘p’ such that if we multiply all digits of ‘p’, we get ‘n’. The result ‘p’ should have minimum two digits. Examples: Input: n = 36 Output: p = 49 // Note that 4*9 = 36 and 49 is the smallest such number In…

We define the smallest positive real number as the number which is explicitly greater than zero and yet less than all other positive real numbers except itself. The smallest positive real number, if exists, implies the existence of the second greater…

题目链接 Description For a positive integer \(n\), let us define \(f(n)\) as the number of digits in base \(10\). You are given an integer \(S(1≤S≤10^8)\). Count the number of the pairs of positive integers \((l,r)\) \((l≤r)\) such that \(f(l)+f(l+1)+-+f…
