若无解或者答案超过100位,输出no solution。 n最大=900,m最大=8100 dp[i][j]表示和为i,平方和为j的最少位数 dp2[i][j]表示和为i,平方和为j的最小首位数 竟然一直在思考有前导0怎么办,最优解肯定不能出现0啊啊啊 #include<cstdio> #include<algorithm> using namespace std; #define N 901 #defi...
Input The first line contains the number of test cases t (no more than 10000). In each of the following t lines there are numbers s1 and s2 (1 ≤ s1, s2 ≤ 10000) separated by a space. They are the sum of digits and the sum of squared digits of the number n. Output For each...
I want to understand that you can break a problem down, select a good algorithm, turn this into functioning (tested) code, understand the time and space complexity of your solution, appreciate any limitations, and understand possible optimizations. If you fell into the ‘trap’ above, it ...
Algorithm for Java Sum of Digits : step 1: Set sum=0 step 2: Read num step 3: Repeat through step-5 while num greater than 0 step 4: temp=num % 10 step 5: sum=sum+temp step 6: num=num/10step 7: Print sum step 8: Exit...

Sum-of-digits function for certain nonstationary bases - Sidorov - 1999 () Citation Context ...se. Here the authors choose the standard base 2 representation of numbers. It is straightforward to generalize their approach for an arbitrary mixed base, and our algorithm is directly applicable. In...
Given an integer number n, return the difference between the product of its digits and the sum of its digits. Example 1: Input: n = 234 Output: 15 Explanation: Product of digits = 2 * 3 * 4 = 24 Sum of digits = 2 + 3 + 4 = 9 ...
A problem that lets the user enter any positive integer, but you do not have to check for this, and then calculates the sum of the digits and displays this to user. For example, if user enters 14503, the outputted sum of the digits would be 13. You need turn in an algorithm, C++...
Then only (part of) integers of digits or less can be represented. However, using the algorithm of this paper we can study the digit sum of integers of as many as [M/9] digits. This algorithm can evaluate the proportion of integers whose digit sum satisfies certain given conditions. The...
