public?static?int[]?SelectionTest(int[]?a){
????????for(int?i?=?0;i<a.length-1;i++){
????????????int?min?=?a[i];
????????????int?Index?=?0;//1
????????????*
????????????*
????????????a[Index]=a[i];//2
????????????a[i]=min;
????????????錯誤在//1這里，如果這層循環沒有比a[i]小的，那么最后就會讓//2處的a[index]=a[i]，
????????????也就是a[0]=a[i]
???????????
