It’s probably wrong when there is some segments having same start time. I run this test case with your code: 10 1 1 1 2 3 3 1 4 3 5 3 6 3 7 8 8 3 9 3 10 Your code output 10 but the answer is actually 9 I have several WA … Read more
double is not enough for the precision you should use high-precision to solve it 6 solved Online Judgement System – Why am I getting Wrong Answer for this thread? [closed]
If you want to make change for the number n, set up an array number_of_coins[n] and fill it in from left to right. number_of_coins[0] is 0, obviously. The next few you can do by hand (although once you have an algorithm it will fill them in automatically). To fill in larger entries m in the … Read more
The API is confusing: What is namelen ? is it the length of the initial prefix of name that is the name of the student? In this case you should allocate one extra byte for the null terminator and copy the name appropriately. is it the maximum length for the student name? Again if this … Read more
This can be solved in Dynamic Programming (DP) by following the recursive formula: D(x) = INFINITY x < 0 D(0) = 0 D(x) = min{ D(x-1), D(x-15), D(x/2) } + 1 In bottom-up DP it will be something like: (pseudo code) D = new int[151] D[0] = 0 for (int i = 1; i <151; … Read more
A difference between your JavaScript and C++ code samples is: the C++ function has just two parameters instead of 3, the map object being managed as a global entity. In some sense, having just 2 parameters is “The Right Thing”. The unordered map is about some internal necessity of the algorithm. Why should user code … Read more
The problem in your code is the way you handle the storing of sates in your memo table. You store only when the result is desired in the for loop and same problem is while returning using the memo table. So, the states which result in false are not stored in your memo until the … Read more
Here is the greedy algorithm – always the best place to start. allocate all teams IF not all sections covered output -1 stop mark all teams non-critical flag_improved = true WHILE( flag_improved == true ) flag_improved = false find most expensive section find most expensive non-critical team on most expensive section IF team found that … Read more
I have solved it. The problem was NoSuchElementException for the line: n=scanner.nextInt(); I have fixed it using: if(scanner.hasNextInt()) { n = scanner.nextInt(); } The code has been accepted by uHunt. solved UVa 562 runtime error. What can I do? [closed]
why is dp initialized to 0? for using for example addition operation dp[i]+=dp[i-2<0?0:i-2]; you should use a valid value not a random value why do we subtract ‘0’*10? for conversion of char to int you substarct the ascii of ‘0’ (0x30) for example ‘1’ /* 0x31 */ – ‘0’ /* 0x30 */ = 1 and … Read more
