Problem:
Given a number n, create and return a new int array of length n, containing the numbers 0, 1, 2, ... n-1. The given n may be 0, in which case just return a length 0 array. You do not need a separate if-statement for the length-0 case; the for-loop should naturally execute 0 times in that case, so it just works. The syntax to make a new int array is: new int[desired_length] (See also: FizzBuzz Code)
fizzArray(4) → {0, 1, 2, 3}
fizzArray(1) → {0}
fizzArray(10) → {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
Solution:
public int[] fizzArray(int n) {
int[] result = new int[n];
for (int i = 0; i < n; i++)
result[i] = i;
return result;
}
public int[] fizzArray(int n) {

for(int i = 0; i < n; i++)
{
result[i] = i;
}
return result;
}
public int[] fizzArray(int n) {

int c=0;
for(int i=0; i < n; i++){
new_int_array[i] = c;
c++;
}
return new_int_array;
}
public int[] fizzArray(int n) {
ReplyDeleteint num=0;
int newarr[]=new int[n];
for(int i=0;i<n;i++)
newarr[i]=num++;
return newarr;
}
public int[] fizzArray(int n)

With Java Stream

int[] arr = IntStream.range(0, n).toArray();
return arr;
