📅  最后修改于: 2021-05-31 22:06:24             🧑  作者: Mango

给定最后的排名“ L”和最后一个排名“ T”的候选人数量,任务是查找考试中的候选人总数。

Input: L = 5, T = 1
Output: 5

Input: L = 10, T = 2
Output: 11

方法:

  1. 假设L = 5且T = 2。
  2. 然后可以有许多可能的等级组合,例如1、2、3、3、5、5。
  3. 因此,现在您可以看到,最后的排名是5,而2名学生排名5,
  4. 因此,候选人总数= 6。
  5. 这可以通过一个简单的公式来理解:
    L+T-1

以下是上述方法的实现。

C++
// C++ program to find total number of candidates
// in an Exam from given last rank
// and Number of student at this last rank.
  
#include 
using namespace std;
  
// Function to find total number of
// Participants in Exam.
int findParticipants(int L, int T)
{
    return (L + T - 1);
}
  
// Driver code
int main()
{
    int L = 10, T = 2;
    cout << findParticipants(L, T);
  
    return 0;
}


Java
// Java program to find total number of
// candidates in an Exam from given last rank 
// and Number of student at this last rank. 
class GFG 
{
  
    // Function to find total number of 
    // Participants in Exam.
    static int findParticipants(int L, int T)
    {
        return (L + T - 1);
    }
  
    // Driver code 
    public static void main(String args[]) 
    {
        int L = 10, T = 2;
        System.out.print(findParticipants(L, T));
    }
}
