I've been into steemit for three weeks now, and I'm really enjoying my time in this community. I get to know a lot of people, and interact with them. What made me love Steemit more is when I see people like @jaycee7viral who holds #mindgamecontest like this. If you haven't known about it yet, and are interested, check the details here. This is just the first one among a series of mind-puzzling competitions he will be conducting in the future.
Here's the problem for Genius Level:

Answer and Explanation
Actually there are two possible solutions for this problem, but I chose to show only one. :)
The man crosses the river with the chicken. This way, since the fox doesn't eat corn, the corn is safe!
The man goes back to the other side.
He brings the corn with him to the destination side of the river.
He then goes back, this time with the chicken because if he leaves it there, the chicken will eat the corn.
Then the man goes to the other side bringing the fox to keep it from eating the chicken.
Then the man goes back to where the chicken is.
And finally he brings the chicken to the other side to complete the mission!
Problem solved! Thank you for going over my way of solving the problem. God bless :)
