在本教程中,我们将讨论一个寻找最大总和增加子序列的程序。
为此,我们将提供一个包含N个整数的数组。我们的任务是从数组中选取元素,这些元素的总和为最大,从而使元素按排序顺序排列
#include <bits/stdc++.h>
using namespace std;
//返回最大和
int maxSumIS(int arr[], int n) {
int i, j, max = 0;
int msis[n];
for ( i = 0; i < n; i++ )
msis[i] = arr[i];
for ( i = 1; i < n; i++ )
for ( j = 0; j < i; j++ )
if (arr[i] > arr[j] &&
msis[i] < msis[j] + arr[i])
msis[i] = msis[j] + arr[i];
for ( i = 0; i < n; i++ )
if ( max < msis[i] )
max = msis[i];
return max;
}
int main() {
int arr[] = {1, 101, 2, 3, 100, 4, 5};
int n = sizeof(arr)/sizeof(arr[0]);
cout << "Sum of maximum sum increasing subsequence is "<<
maxSumIS( arr, n ) << endl;
return 0;
}输出结果
Sum of maximum sum increasing subsequence is 106
