使用C++编写的矩阵中找到具有最大和的一对的算法

Input : matrix[m][n] = {
   { 3, 5, 2 },
   { 2, 6, 47 },
   { 1, 64, 66 } }

Output : 130
Explanation : maximum sum is 130 from element pair 64 and 66.

Input : matrix[m][n] = {
   { 55, 22, 46 },
   { 6, 2, 1 },
   { 3, 24, 52 } }
Output : 107
Explanation : maximum sum is 130 from element pair 55 and 52.

#include <bits/stdc++.h>
using namespace std;

int main() {
   int m = 3, n = 3;
   // initialising matrix with values
   int matrix[m][n] = {
      { 55, 22, 46 },
      { 6, 2, 1 },
      { 3, 24, 52 }
   };

   // initialising MAX1 and MAX2 to keep two maximum numbers.
   int MAX1 = INT_MIN;
   int MAX2 = INT_MIN;
   int result;

   for (int i = 0; i < m; i++) {
      for (int j = 0; j < n; j++) {
      // check if the element is greater than MAX1.
         if (matrix[i][j] > MAX1) {
            MAX2 = MAX1;
            MAX1 = matrix[i][j];
         }
         // check if the current element is between MAX1 and MAX2.
         else if (matrix[i][j] > MAX2 && matrix[i][j] <= MAX1) {
            MAX2 = matrix[i][j];
         }
      }
   }
   // calculating maximum sum by adding both maximum numbers.
   result = MAX1 + MAX2;
   cout << "maximum sum in Matrix : " << result ;

   return 0;
}

maximum sum in Matrix : 107
