tenRun challenge

Hi,

I am working on below challenge

http://codingbat.com/prob/p199484

Psedo code description of approach :
1. create new array of given array size
2. loop given array in for loop
3. check each element value not greater than 10
4. if yes multiply by 10
5 if no give same value from given array to new array

I wrote my code as below

public int[] tenRun(int[] nums) {
  
  
  int len =nums.length;
  int[] arr=new int[len];
  for(int i=0;i<len;i++){
    if(nums[i]<10){
    arr[i]=nums[i]*10;
    }
    else{
        arr[i]=nums[i];
    }
  }
  return arr;
}

I am  not passing all tests
Expected      Run            
tenRun([2, 10, 3, 4, 20, 5]) → [2, 10, 10, 10, 20, 20]      [20, 10, 30, 40, 20, 50]      X      
tenRun([10, 1, 20, 2]) → [10, 10, 20, 20]      [10, 10, 20, 20]      OK
