An integer is divisible by 3 if the sum of its digits is also divisible by 3. For example, 3702 is divisibleby 3 and 12(3+7+0+2) is also divisible by 3. This property also holds for the integer 9.In this problem, we will investigate this property for…
You are given two integers l l and r r (l≤r l≤r ). Your task is to calculate the sum of numbers from l l to r r (including l l and r r ) such that each number contains at most k k different digits, and print this sum modulo 998244353 998244353 . For…
