IterTools product in Julia
I would like to produce lists of 0 and 1 in Julia using IterTools.
For example, in Python I can do:
for bits in itertools.product([0, 1], repeat=5):
print(bits)
This will produce
(0, 0, 0, 0, 0)
(0, 0, 0, 0, 1)
(0, 0, 0, 1, 0)
(0, 0, 0, 1,…

Python: Given 2 binary strings s and t, print minimum number of adjacent swaps to convert s to t
For example if s = "1000000111" and t = "0111000001" the output should be 11. Below is my solution but it gives a time limit exceeded error so I am looking for a faster method. The length of string is less than 10^6.
T = int(input())
