一共可以排25*24*23*22*21*20 = 127512000组
用JAVA实现
public class Cat {
public static void main(String[] args) {
int[] ary = new int[25];
for(int i = 0; i < ary.length; i++){
ary[i] = i+1;
}
for(int i = 0; i < ary.length; i++){
for(int j = 0; j < ary.length; j++){
if(i != j){
for(int k = 0; k < ary.length; k++){
if(k != i && k != j){
for(int m = 0; m < ary.length; m++){
if(m != i && m != j && m != k){
for(int n = 0; n < ary.length; n++){
if(n != i && n != k && n != j && n != m){
for(int l = 0; l < ary.length; l++){
if(l != i && l != j && l != k && l != m && l != n){
System.out.println(ary[i] + "," + ary[j] + ","
+ ary[k] + "," + ary[m] + "," + ary[n] + "," + ary[l]);
}
}
}
}
}
}
}
}
}
}
}
}

太多了,总之就是先拿出一个数字出来,然后后面逐个按照次序排列
用JAVA实现
public class Cat {
public static void main(String[] args) {
int[] ary = new int[25];
for(int i = 0; i < ary.length; i++){
ary[i] = i+1;
}
for(int i = 0; i < ary.length; i++){
for(int j = 0; j < ary.length; j++){
if(i != j){
for(int k = 0; k < ary.length; k++){
if(k != i && k != j){
for(int m = 0; m < ary.length; m++){
if(m != i && m != j && m != k){
for(int n = 0; n < ary.length; n++){
if(n != i && n != k && n != j && n != m){
for(int l = 0; l < ary.length; l++){
if(l != i && l != j && l != k && l != m && l != n){
System.out.println(ary[i] + "," + ary[j] + ","
+ ary[k] + "," + ary[m] + "," + ary[n] + "," + ary[l]);
}
}
}
}
}
}
}
}
}
}
}
