The sample output was still wrong.

The description of problem is not so clear.
Z = Z * Z + C means:
Given a complex number C = 1 + i
iteration 1: Z = 0 + C = 1 + i, d = sqrt(1 + 1) = sqrt(2);
iteration 2: Z = (1 + i) * (1 + i) + (1 + i) = 1 + 3i, d = sqrt(1 + 9) = sqrt(10);
...

It can be solved using greedy algorithm, why?

The solution on uDebug gives different answer which I thought wrong.

There are so many ads, please administrator clear it all!

The output specification is not so clear.
You should print a '\n' at end of EVERY line of output even the last line.
I didn't print a '\n' at last line that brings to me many WAs.

The test data generator. #include <iostream> #include <algorithm> #include <ctime> #include <random> using namespace std; int main(int argc, char *argv[]) { string cards = "7J93JQKA23456789T8QKA23456789TJQKA23456789TJQKA2T456"; for (int i = 1; i <= 100; i++) { shuffle (cards.begin(), cards...

The statement of problem is not so clear, I spent some time on Internet to figure out the rule of Clock game. The rule in this problem differs from regular rule. you should beware of two points below: 1. When you deal the cards, you should place four card at one clock, then four cards at two clock, ...

Test data generator. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int gcd(int a, int b) { int t; while (a % b) t = a, a = b, b = t % b; return b; } int plaincode[80], ciphercode[80]; int main(int argc, char *argv[]) { string letters = "_abcdefghijklmnopqrstuvwxyz...

There is test data generator wrote in C++ below. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; const int MAX_CASES = 100, MAX_OP = 60, MAX_STACK = 10, BASE = 10; int main(int argc, char *argv[]) { cout << MAX_CASES << "\n\n"; srand(time(NULL)); for (int c = 1...

The format of Sample Input is wrong, there is no r in first line.

Poor problem statement.
"but if you reach the end of a test case and not find an expression not properly nested and some brackets are even opened you must print number_of_chars_of_the_case + 1"

I misunderstood the problem, the statement: "The snail has a fatigue factor of 10%, which means that on each successive day the snail climbs 10% 3 = 0.3 feet less than it did the previous day." means every day, the snail lost 10% of climbed distances, no matter climbed distances bellow zer...

The input format is not so friendly.

Use ternary search. The code below is test data generator. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main(int argc, char *argv[]) { srand(time(NULL)); for (int c = 1; c <= 100; c++) { int l = rand() % 1000; int w = rand() % 1000; if (l < w) swap(l, w); if (l ==...
