Find number of candidates in the Exam
Given the last rank ‘L’ and number of candidates at the last rank ‘T’, the task is to find the total number of candidates in Exam.
Input: L = 5, T = 1 Output: 5 Input: L = 10, T = 2 Output: 11
Approach:
- Suppose L = 5 and T = 2.
- Then there can be many possible rank combinations, like 1, 2, 3, 3, 5, 5.
- So now in this, as you can see the last rank is 5 and there are 2 students at rank 5,
- Therefore, total number of candidates = 6.
- This can be understood by a simple formula:
L+T-1
Below is the Implementation of Above Approach.
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 <iostream> 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; } |
