problem BOJ 2869 solution iteration height 1 A 2 A + (B - A) 3 A + 2 * (B - A) … … condition for arrival: \(V >= A + ((iteration) - 1) * (A - B)\) \((V-A)/(A-B) + 1 >= (iteration)\) in c++, the iteration can be ex...

problem The follwing code, a part of solution for BOJ 2753 does not print as expected. cout << (!(year % 4) && (year % 100)) || !(year % 400); solution Refer to c++ operator precedence. Operater ‘«’ has greater precedence than ‘||’. Therefore, the code above will behave as following: (cout << (!(year % 4) && (year %...

problem The codes below are parts of the solution for BOJ 4344 ‘code 1’ prints as inteded whereas ‘code 2’ does not. // code 1 cout << (float) ctr / N * 100 << '\n'; // code 2 cout << ctr / N * 100.0 << '\n'; According to c++ operator precedence, associativity for multiplication and division is ‘left to right’. Therefor...

problem Tried to print empty array, but the result wasn’t empty. int ctr[10]; for(int i = 0; i < 10; ++i){ cout << ctr[i] << '\n'; } solution C/C++ arrays are not initialized upon declaration. Initialize at least 1 element to set the others as 0. int ctr[10] = {0}; for(int i = 0; i < 10; ++i){ cout << ctr[i] &...
