用Go語言實現(xiàn)動態(tài)規(guī)劃問題的時候在二維數(shù)組的傳參改變這個地方有了點疑惑，查了會兒資料，然后達到了目的(其實還是想知道切片的話可不可以二維)，所以記錄一下
package main
import "fmt"
//n=7
func matrixChainOrder(p []int,m *[7][7]int,s *[7][7]int,n int){
for i:=0;in;i++{
m[i][i] = 0
}
for l:=2;ln;l++{
for i:=1;in-l+1;i++{
j:=i+l-1
m[i][j] = 10000000
for k:=i;k=j-1;k++{
q:=m[i][k]+m[k+1][j]+p[i-1]*p[k]*p[j]
if qm[i][j]{
m[i][j] = q
s[i][j] = k
}
}
}
}
// fmt.Println(m[1][6])
}
func main(){
p:=[]int {30,35,15,5,10,20,15}
var m [7][7]int
var s [7][7]int
matrixChainOrder(p,m,s,7)
fmt.Println(m[1][6])
}
func myfun(a *[]int) {
fmt.Print(a)
//a[0] = 5
(*a)[0] = 5
//fmt.Print("here", a, "\n")
}
func test() {
a1 := 1
b1 := 2
var a []*int = []*int{a1, b1}
fmt.Print(a)
}
func main() {
var a []int = []int{1, 2, 3, 4}
myfun(a)
fmt.Print(a)
test()
}
