You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 1444.go
    path of file: ./repos/Leetcode/src/1444-Number-of-Ways-of-Cutting-a-Pizza
    
    the code of the file until where you have to start completion: var r, c, mod int
var dp [][][]int
var g [][]int


func ways(pizza []string, k int) int {
    r, c, mod = len(pizza), len(pizza[0]), 1000000007
    dp = make([][][]int, r)
    g =
    
func ways(pizza []string, k int) int {
    r, c, mod = len(pizza), len(pizza[0]), 1000000007
    dp = make([][][]int, r)
    g = make([][]int, r + 1)
    for i := 0; i < r; i++ {
        dp[i] = make([][]int, c)
        for j := 0; j < c; j++ {
            dp[i][j] = make([]int, k)
        }
    }
    for i := 0; i <= r; i++ {
        g[i] = make([]int, c + 1)
    }
    for i := r - 1; i >= 0; i-- {
        for j := c - 1; j >= 0; j-- {
            g[i][j] = g[i][j + 1] + g[i + 1][j] - g[i + 1][j + 1]
            if pizza[i][j] == 'A' {
                g[i][j] += 1
            }
        }
    }
    return dfs(0, 0, k - 1)
