If the integersList has only one item, this piece of code "integersList.join().split(digitsList[i]).length -1" does not give zero?

If you're entirely stumped it's not a bad idea actually to unlock the solution. However, make sure you take the time to analyze the solutions of other users until you understand what you were getting stuck on. Once you feel like you have a solid understanding of what you were missing, attempt to solve the kata again (even without the reward incentive) without having to look back at the solutions. Otherwise, there's not much benefit to unlocking them. If you're concerned about losing out on potential honor, there's over 5k challenges on the website, so it's not really a big deal if you can't get points for a few of the harder ones.

Remember to utilize the language's documentation and other resources if you get stuck before unlocking the solution though. Often times what I'll do is bookmark the challenge I'm stuck on, and spend some time doing research on it. If it still doesn't come to me, I'll bookmark the kata and attempt to solve it later, usually I come back at it later with some new ideas. In most cases, this works out for me. But, I've had to unlock solutions a few times, especially when I first started the 4kyu+ optimization challenges.

thanks buddy

Rote learning is always dangerous because it often leads to "going through the motion" scenario.
You see but do not perceive.
If you do not have photographic memory, I suggest that you repeat the exercises few weeks later after your memory of the respective solutions fade away.

The way I see it is that as long as you learn from doing so, then that's all that really matters. I've done it myself once but made sure I fully understood it, made notes and reflected on it before I moved on.

No, but you should spend time studying other users solutions.

Don't post code here, use that kata discourse and mark your post as having spoiler content.

i have to find an integer which appears an odd number of times in an array. what am i doing wrong.help!

public class FindOdd
{
public static int findIt(int[] a)
{
int odd,b;
for(int i=0;i<a.length;i++)
{
odd=1;
b=a[i];
for(int j=i+1;j<a.length;j++)
{
if(b==a[j])
{
odd++;
}
}
if(odd%2!=0)
break;
else
continue;
}
return b;
}
}

I have passed 28 tests but failed 4 tests for - "Playing with digits" kata.
I don't find the correct solution anywhere on the site.
Wanted to check if the correct solution is available after attempting a kata or no?

Write in that kata's discussion, not here. And mark your post as having spoiler content there (can't be done here).

is this a bad habit that if i can't solve a kata for 1 or 2 days than i unclock the solution and practice and learn from it afterwards?

i have passed 26 tests but 6 tests are failing plz tell me what am i doing wrong

this is my code of "Split an array" kata...

function split(arr, prop) {

//ceate an array

let returnArray = [[],[]];

//iterate through all the object in the array

for(let i = 0; i < arr.length; i ++){
//compare the prop

if(arr[i][prop] && arr[i][prop] !== false && arr[i][prop] !== 0 && arr[i][prop] != "" && arr[i][prop] != null && arr[i][prop] !== undefined && arr[i][prop] != NaN){

  //if it is true than first object of the array is the given object 

  returnArray[0].push(arr[i]);

} 

if((arr[i][prop] === null && arr[i][prop] !== true && arr[i][prop] == "" && arr[i][prop] === undefined && arr[i][prop] == NaN) || !arr[i][prop] || arr[i][prop] === 0){

  //if it is false than second object of the array is the given object

  returnArray[1].push(arr[i]);

}
	
}

//return the array	
return returnArray;

}

is it a bad habit that if I could not solve one problem for 1 or 2 days than i should click on unlock solution??

help me bro I search about truthy and falsy after that i have managed to pass 26 test but still 6 tests are not passing i am very serious about this kata and i don't wanna look at the solution....... plz give me some hints
