In Level 2 of the river crossing game, we need to transport three murderers and three missionaries across the river. If the number of murderers exceeds that of missionaries on either side of the river, the missionaries will be in peril. Here's the solution and some helpful illustrations:
Step 1: Transport 2 murderers across, then return 1 murderer.
Step 3: Send back 1 missionary and ferry the remaining murderer across. Problem solved!
Step 3: Move 1 murderer and 1 missionary back.
Step 4: Transport 2 missionaries across and send 1 murderer back.
Step 5: Transfer 2 murderers across, then return 1.
Step 6: Bring the remaining 2 murderers across to complete level 2.
