Below that boolean expression, add another boolean expression that checks if the player's `x` position is greater than or equal to the platform's `x` position minus half of the player's width.

You should have a boolean expression that checks if the player's `x` position is greater than or equal to the platform's `x` position minus half of the player's width.
You should have a boolean expression that checks if the player's `x` position is greater than or equal to the platform's `x` position minus the player's width divided by `2`.

Add one last boolean expression that checks if the player's `x` position is less than or equal to the sum of the platform's `x` position plus the platform's width minus one-third of the player's width.
Add one last boolean expression that checks if the player's `x` position is less than or equal to the sum of the platform's `x` position plus the platform's width minus one-third of the player's width. Use the division operator (`/`) to calculate a third of the player's width.
