The earlier code fails to output the right index for following input: (Note that the first value '1' is repeated)
array = [1, 1, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 6, 6, 6]
firstOccurance(array, 1)
* Update bst.py
Removing redundant checks moving root is None check in recur_search/recur_size.
Similar change could be done in recur_insert.
```python
def insert(self,data):
self.root = self.recur_insert(self.root, data)
def recur_insert(self, root, data):
if root is None:
return Node(data)
if root.data == data:
return # Do Nothing
elif data < root.data:
root.left = self.recur_insert(root.left, data)
else:
root.right = self.recur_insert(root.right, data)
```
* Update first_occurance.py
Incorporated review comments for keon#206
* Update first_occurance.py
Address Keon Review comments.
* Update first_occurance.py
Fixing the infinite loop. It is good idea to keep the following loop condition always in binary search and incorporating additional conditions if required within the while lo <= hi: loop instead of writing multiple variants as https://leetcode.com/articles/introduction-to-binary-search/
lo, hi = 0, len(array) - 1

* Update test_stack.py

* Update priority_queue.py (keon#273)
* Update priority_queue.py
- refactor `insert` and `delete` -> `push` and `pop`. Because `pop` seems more natural while returning the deleted item (rather than `delete`)
- `push` now takes data and priority(optional), and constructs a `PriorityQueueNode` inside the method for inserting. This simplifies the usage.
- used `collections.deque()` for O(1) popleft operation.
- add `__repr__` method.

* Update bst.py
* Update topsort.py
The original algo is wrong because it is using BFS, it should use DFS instead.
A counter-example is provided below:
depGraph = {
"a" : [ "b" ],
"b" : [ "c" ],
"c" : [ 'e'],
'e' : [ 'g' ],
"d" : [ ],
"f" : ["e" , "d"],
"g" : [ ]
}
given = [ "b", "c", "a", "d", "e", "f", "g" ]
The output of ret_dep_graph() is: ['e', 'g', 'c', 'b', 'a', 'd', 'f']
Clearly, 'g' has to be done before 'e'.

Removing redundant checks moving root is None check in recur_search/recur_size.
Similar change could be done in recur_insert.

self.root = self.recur_insert(self.root, data)
def recur_insert(self, root, data):
if root is None:
return Node(data)
if root.data == data:
return # Do Nothing
elif data < root.data:
root.left = self.recur_insert(root.left, data)
else:
root.right = self.recur_insert(root.right, data)
```

Fixing the infinite loop. It is good idea to keep the following loop condition always in binary search and incorporating additional conditions if required within the while lo <= hi: loop instead of writing multiple variants as https://leetcode.com/articles/introduction-to-binary-search/
lo, hi = 0, len(array) - 1

* Update test_stack.py

* Update priority_queue.py (keon#273)
* Update priority_queue.py
- refactor `insert` and `delete` -> `push` and `pop`. Because `pop` seems more natural while returning the deleted item (rather than `delete`)
- `push` now takes data and priority(optional), and constructs a `PriorityQueueNode` inside the method for inserting. This simplifies the usage.
- used `collections.deque()` for O(1) popleft operation.
- add `__repr__` method.

The original algo is wrong because it is using BFS, it should use DFS instead.
A counter-example is provided below:
depGraph = {
"a" : [ "b" ],
"b" : [ "c" ],
"c" : [ 'e'],
'e' : [ 'g' ],
"d" : [ ],
"f" : ["e" , "d"],
"g" : [ ]
}
given = [ "b", "c", "a", "d", "e", "f", "g" ]
The output of ret_dep_graph() is: ['e', 'g', 'c', 'b', 'a', 'd', 'f']
Clearly, 'g' has to be done before 'e'.
