Sample Input #1
make(4)
Sample Output #1
{"0","1","2","3"}
public class StringArrayOfNumbers {
static int testcase1 = 10;
public static void main(String args[]){
StringArrayOfNumbers testInstance = new StringArrayOfNumbers();
String[] result = testInstance.make(testcase1);
System.out.println(result);
}
public String[] make(int num){
int n=0;
String n1="n";
String[] arr=new String[num];
for(int i=0;i<num;i++){
arr[i]=n1;
n=n+1;
}
return arr;
}
}
when i am trying to run code it prints only 4 times n , how to initialise this n? also without using any string library functions?
Testcase Pass/Fail Parameters Actual Output Expected Output
n1
is a String
which has the value " n
" in it.
whereas n
is a variable whose value varies from 0
to num - 1
.
SO you might want to assign n
instead of n1
.
int n=0;
String[] arr=new String[num];
for(int i = 0; i < num; i++){
arr[i]= n;
n = n + 1;
}
If you look closely, n
and i
have the same value, you don't need n
too.
String[] arr=new String[num];
for(int i = 0; i < num; i++){
arr[i] = i;
}
i'm not sure of what you are asking for, but the result should be this :
public String[] make(int num) {
int n = 0;
//String n1 = "n";
String[] arr = new String[num];
for (int i = 0; i < num; i++) {
arr[i] = String.valueOf(n);
n = n + 1;
}
return arr;
}
