asked on array6 challenfge
Hi,
I am working on below challenge.
http://codingbat.com/prob/p108997
Psedo code:
1. create new array of the portion of original array length
2. fill new array with rest of the elements
3. check to see if it has 6 if yes return true if no return false
4. retrun above boolean
I wrote my code as below

4. retrun above boolean
I wrote my code as below
public boolean array6(int[] nums, int index) {
int len=nums.length-index;
int[] num=new int[len];
//fill without using for loop but recursive way
if(num.length==0){
return false;
}
if(num.length==1&&!num.contains(6)){
return false;
}
if(num.length==1&&num.contains(6)){
return true;
}
return null;
}

public boolean array6(int[] nums, int index) {
if(index>nums.length()){
return false;
}
else if(nums[index]==6){
return true;
}
else return arrays6[nums,index+1];
}
/*- check if index >= array size
- if yes, return false
- check if nums[index] == 6
- if yes, return true,
- return array6 function call passing nums and index+1*/
above gives below error.
Compile problems:please advise
Error: else return arrays6[nums,index+1];

Syntax error on token ",", . expected

public boolean array6(int[] nums, int index) {
if(index>=nums.length){
return false;
}
else if(nums[index]==6){
return true;
}
else return array6(nums,index+1);
}
above passed all tests.
any improvements or alternate approaches?
Your code is good. My personal preference is to omit the elses.
public boolean array6(int[] nums, int index) {
if(index>=nums.length){
return false;
}
if(nums[index]==6){
return true;
}
return array6(nums,index+1);
}
public boolean array6(int[] nums, int index) {
IntStream.of(nums).anyMatc
}
