Write a function to print all possible subarrays using recursion

Solution

def printSubArrays(arr, start, end):
    if end == len(arr):
        return
    elif start > end:
        return printSubArrays(arr, 0, end + 1)
    else:
        print(arr[start:end + 1])
        return printSubArrays(arr, start + 1, end)
arr = [1, 2, 3]
printSubArrays(arr, 0, 0)
