二维数组中的查找-golang

func searchArray(array [][]int, target int) bool {
    if len(array) == 0 || len(array[0]) == 0{
        return false
    }
    i, j := 0, len(array[0])-1

    for i < len(array) && j >= 0{
        if array[i][j] == target{
            return true
        }
        if array[i][j] > target{
            j--
            continue
        }
        if array[i][j] < target{
            i++
        }
    }
    return false
}
