Here is my solution https://www.codechef.com/viewsolution/16015394 it is similar to https://www.codechef.com/viewsolution/16009178 but mine gets TLE

```
temp_a = a[0:i] + a[(i+1):len(a)]
```

Can you once confirm the complexity of the above operation? I think its O(N) in itself and gives your code complexity of O({N}^{2}) in itself.

Also See this statement in your code:

** for i in range(len(a)) :**

function **len** is itself linear in nature. Every time in for loop iteration len function is evaluated to check the limit and hence, time complexity is getting increased by a factor **n**,which ultimately slows down your program.

Its a common mistake, just store length in a variable before iterating and then use that variable inside loop.

Even after keeping variable for len function, your program timed out.I compared both the solutions and logic is more or less same.One thing which you are doing is unnecessary typecasting of strings to int, which overkill.

Just use it as string variable for comparison. Here is the link for your ACed solution.

yes the complexity of the statement is O(n)

Thank You
