單例模式

GIT和SVN區別

編程題

用string 相加，不能用lib

兩個數組判斷，是否B屬於A的子類，有返回第一個數組的下標，無則返回-1


pubilc Sting add(Sting numberA,String numberB){
	
}

	system.out.println(add("123456789123456789123456789","123456789123456789123456789"));  //24676895858588768055576705442138576768
	system.out.println(add("1","2")); //3
	system.out.println(add("A","1")); //ERROR
	
pubilc int sub(int A[],int B[]){

}

	system.out.println(sub("{4,5,6,7,8}","{5,6}"));  //return 1
	system.out.println(sub("{4,5,6,7,8}","{5,4}")); //return -1
	system.out.println(sub("{4,5,6,7,8}","{6,7,8}")); //return 2
