def binary_search(arr, target):
# TODO: implement
pass
```<end_of_turn>
<start_of_turn>model
I'll analyze this code and provide an improved version.
**Analysis:** Implemented binary search algorithm with proper logic and edge case handling.
**Improved code:**
```python
def binary_search(arr, target):
left, right = 0, len(arr) - 1
while left <= right:
mid = (left + right) // 2
if arr[mid] == target:
return mid
elif arr[mid] < target:
left = mid + 1
else:
right = mid - 1

I'll analyze this code and provide an improved version.
**Analysis:** The bug is list append: using 'list = list + [x]' instead of 'list.append(x)'.
**Improved code:**
```python
def function_v1035():

**Improved code:**
```python
def merge_sort(arr):
if len(arr) <= 1:
return arr
mid = len(arr) // 2
left = merge_sort(arr[:mid])
right = merge_sort(arr[mid:])
return merge(left, right)
def merge(left, right):
result = []
i = j = 0
while i < len(left) and j < len(right):
if left[i] <= right[j]:
result.append(left[i])
i += 1
else:
result.append(right[j])
j += 1
result.extend(left[i:])
result.extend(right[j:])
return result

Implement binary search in Python
Input code:
```python
def binary_search(arr, target):
# TODO: implement
pass
```<end_of_turn>
<start_of_turn>model
I'll analyze this code and provide an improved version.
**Analysis:** Implemented binary search algorithm with proper logic and edge case handling.
**Improved code:**
```python
def binary_search(arr, target):
left, right = 0, len(arr) - 1
while left <= right:
mid = (left + right) // 2
if arr[mid] == target:
return mid
elif arr[mid] < target:
left = mid + 1
else:
right = mid - 1
return -1

if visited is None:
visited = set()
visited.add(start)
print(start)
for neighbor in graph[start]:

Optimize this loop implementation
Input code:
```python
def fib(n):
if n <= 1:
return n
return fib(n-1) + fib(n-2)
```<end_of_turn>
<start_of_turn>model
I'll analyze this code and provide an improved version.
**Analysis:** Optimized by: cache results
**Improved code:**
```python
from functools import lru_cache
@lru_cache(maxsize=None)
def fib(n):
if n <= 1:
return n
return fib(n-1) + fib(n-2)

I'll analyze this code and provide an improved version.
**Analysis:** Improved by: split long lines
**Improved code:**

I'll analyze this code and provide an improved version.
**Analysis:** The bug is assignment: using '==' instead of '='.
**Improved code:**
```python
def function_v210():
# Fixed: =
