Hijack attempt -- explain code

[cj_in da house]

can anyone explain what this part of the for loop is doing?

int findMode(int *array, int size)
{
    int mode = -1, position = 0, highest;
    int frequency[constant];

    for(int i = 0; i < size; i++)        //initailize all frequencies to 0
        *(frequency + i) = 0;

    
    for (int k = 0; k < size; k++)
    {
        for (int i = 1; i < size; i++)
        {
            if (*(array + k) == *(array + i) && &*(array + k) != &*(array + i))  //avoid counting itself in the scan
                *(frequency + k) += 1;                 //increment the frequency of current number
        }
    }
    
    highest = *(frequency + 0);
    for (int count = 1; count < size; count++)    // get position of highest number
    {
        if (*(frequency + count) > highest)
        {
            highest = *(frequency + count);
            position =+ count;                //get postion in frequency array, to put into numbers array
        }
    }

    for(int i = 0; i < size; i++)
        if(*(frequency + i) != *(frequency + (i + 1)) && (i + 1) < size)
        {
            mode = *(array + position);
            return mode;    //returns number that occurs most 
        }
    return mode;        //returns -1 if all same frequency
