[Solved] How to remove “end of non-void function” error in c++? [duplicate]

by


Return some value via return statement regardress of value of lookup[i][j].

For example, return 0 because I don’t know the correct value to return.

int f(long long int arr[], long long int x, long long int y)
{
    long long int i = x, j = y;
    if(lookup[i][j] == 0)
    {
        if(i == j)
            lookup[i][j] = arr[i];
        else
            lookup[i][j] = min(f(arr, i, j-1), arr[j]);
        return 0; /* add this line */
    }
    else
        return (lookup[i][j]);
}

Alternatively, I guess the function should be like this:

int f(long long int arr[], long long int x, long long int y)
{
    long long int i = x, j = y;
    if(lookup[i][j] == 0)
    {
        if(i == j)
            lookup[i][j] = arr[i];
        else
            lookup[i][j] = min(f(arr, i, j-1), arr[j]);
    }
    /* remove else here */
    return (lookup[i][j]);
}
