Yes, such a subarray is called a contiguous subarray. A simple algorithm to find a contiguous subarray that adds up to a specific sum is the sliding window technique:
Here's the implementation of the algorithm in Python:
def find_contiguous_subarray(arr, target_sum):
left, right = 0, 0
sum = arr[left]
while right < len(arr):
if sum == target_sum:
return arr[left:right+1]
elif sum < target_sum:
right += 1
if right < len(arr):
sum += arr[right]
else:
sum -= arr[left]
left += 1
return None
The function takes an array, arr, and a target sum, target_sum, as input and returns a contiguous subarray that adds up to the target sum. If no such subarray is found, it returns None.
