A possible way to merge two sorted arrays in Python is to use a two-pointer approach, where we iterate over both arrays in parallel, comparing the values at each index and inserting the smaller value into a new array. Here's an example implementation:
def merge_sorted_arrays(arr1, arr2):
# initialize pointers for both arrays
i = 0
j = 0
merged = []
# compare the values at the current indices and add the smaller
# value to the merged array, advancing the corresponding pointer
while i < len(arr1) and j < len(arr2):
if arr1[i] < arr2[j]:
merged.append(arr1[i])
i += 1
else:
merged.append(arr2[j])
j += 1
# add any remaining values from the first array
while i < len(arr1):
merged.append(arr1[i])
i += 1
# add any remaining values from the second array
while j < len(arr2):
merged.append(arr2[j])
j += 1
return merged
This implementation has a time complexity of O(n), where n is the total number of elements in the two arrays.
