+# Leetcode using AI :robot:
+GPT-2 Model for Leetcode Questions in python 
 
-Idea is to build a model which will take keywords as inputs and generate sentences as outputs. 
+**Note**: the Answers might not make sense in some cases because of the bias in GPT-2
 
-### Model:
+**Contribtuions:** If you would like to make the model better contributions are welcome Check out [CONTRIBUTIONS.md](https://github.com/gagan3012/project-code-py/blob/master/CONTRIBUTIONS.md)
 
-Two Models have been built: 
+### 📢 Favour:
 
-- Using T5-base size = 850 MB can be found here: https://huggingface.co/gagan3012/keytotext
-- Using T5-small size = 230 MB can be found here: https://huggingface.co/gagan3012/keytotext-small
+It would be highly motivating, if you can STAR⭐ this repo if you find it helpful.
 
-#### Usage:
+## Model
 
+Two models have been developed for different use cases and they can be found at https://huggingface.co/gagan3012
+
+The model weights can be found here: [GPT-2](https://huggingface.co/gagan3012/project-code-py) and [DistilGPT-2](https://huggingface.co/gagan3012/project-code-py-small)
+
+### Example usage:
 ```python
 from transformers import AutoTokenizer, AutoModelWithLMHead
 
-tokenizer = AutoTokenizer.from_pretrained("gagan3012/keytotext-small")
+tokenizer = AutoTokenizer.from_pretrained("gagan3012/project-code-py")
+
+model = AutoModelWithLMHead.from_pretrained("gagan3012/project-code-py")
+```

+Write a function to delete a node in a singly-linked list. You will not be given access to the head of the list, instead you will be given access to the node to be deleted directly. It is guaranteed that the node to be deleted is not a tail node in the list.

+### Answer:
+
+```python
+""" Write a function to delete a node in a singly-linked list. You will not be given access to the head of the list, instead you will be given access to the node to be deleted directly. It is guaranteed that the node to be deleted is not a tail node in the list.
+
+For example,
+a = 1->2->3
+b = 3->1->2
+t = ListNode(-1, 1)
+
+Note: The lexicographic ordering of the nodes in a tree matters. Do not assign values to nodes in a tree.
+Example 1:
+
+Input: [1,2,3]
+Output: 1->2->5
+Explanation: 1->2->3->3->4, then 1->2->5[2] and then 5->1->3->4.

+All nodes are distinct.
