Analyze the following C++ function and determine what problem it solves:

int solve(vector<int> &v, int m){
    int n=v.size();
    vector<int> preMin(n);
    preMin[0]=v[0];
    vector<int> sufMin(n);
    sufMin[n-1]=v[n-1];
    for(int i=1;i<n;i++){
        preMin[i]=min(preMin[i-1], v[i]);
    }
    for(int i=n-2;i>=0;i--){
        sufMin[i]=min(sufMin[i+1], v[i]);
    }
    int ans =INT_MAX;
    int i=0;
    int j=m-1;
    while(i<=n-m){
        ans = min(ans,preMin[i]*sufMin[j]);
        i++;
        j++;
    }
    return ans;
}

Problem Statement:

Given a vector v of integers and an integer m, the function constructs two auxiliary arrays:

• preMin: prefix minimum array where preMin[i] stores the minimum value from index 0 to i
• sufMin: suffix minimum array where sufMin[i] stores the minimum value from index i to n-1

The function then slides a window of size m across the array and for each window position, computes the product of:

• The minimum element in all elements before the window
• The minimum element in all elements after the window

What does this function return?
