Solution - Codeforces 1217E Sum Queries? 对于这个“好的”的判定条件看起来有点奇怪,不妨结合上题目要求的“最小sumsum”一起考虑。 因为要最小化spsp,所以一个比较直观的想法是先从选的数个数入手。 考虑到如果选的只有11个数aiai,那么sum=aisum=ai,一定是好的,排除。 如果选的是22个数ai,...
A complex problem, a complex solution... Consider another way to define the sum of powers of natural numbers, using ss as a parameter: ζ(s)=1−s+2−s+3−s+4−s+…ζ(s)=1−s+2−s+3−s+4−s+… The function ζ(s)ζ(s) converges for any s>1s>1, which, usin...
first of all thanks for your solution.. I have tested your code.. we have to use equality on each three for loop for(ll i = 0; i<=n;i++){ for(ll cur_sum = 0; cur_sum <= max_sum; cur_sum++){ for(ll j = 0; j<=max_number; j++){ d[i+1][cur_sum + j] += d...

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 Result = 24 - 9 = 15 ...

matrix = [ [12, 1, 1, 1], [13, 10, 1, 1], [40, 1, 1, 12] ] Solution: We pick 12 from 1st row Now we cannot pick 13 from 2nd row as the column has already been used. Therefore, will pick 10 in 2nd row Now we can either pick 1 or 12 from 3rd row as 1st and 2n...
I have array with N numbers and I'm allowed to add (),+-* between to generate max sum. Unary operator is not allowed. I know the solution for only positive numbers but I don't know how to handle negatives. Could you please give me any hints or solution?
The solution the interviewer expected: approach: Map-Reduce: send a map program to all the nodes where the map function calculates the following : (number,count(number)) next is the reduce phase where we use the following hashing algorithm in order to assign the above-calculated info in vario...
