Hello Masters,
This is from a beginner in go. Please read the code for Swapping a 64 element array using two 32 element arrays. I have used two ways (OPTIONs), one is working, the other is not. Please tell me where I am wrong and what is the real concept in this language.
Thank You.
package main
import "fmt"
func main() {
var i int
X := make([]byte, 64)
for i = 0; i < 32; i++ {
X[i] = 0; X[32+i] = 1;
}
fmt.Println(X)
//OPTION_1--------------------------------------------------
L := make([]byte, 32)
R := make([]byte, 32)
for i = 0; i < 32; i++ {
L[i] = X[i]; R[i] = X[32+i];
}
//OPTION_2--------------------------------------------------
// L := X[0:32]
// R := X[32:64]
//--------------------------------------------------
fmt.Println(L)
fmt.Println(R)
//COPYING--------------------------------------------------
/*
for i = 0; i < 32; i++ {
X[i] = R[i]
X[32+i] = L[i]
}
*/
copy(X[0:32], R[:])
copy(X[32:64], L[:])
fmt.Println(X)
}
