What "three second rule" means in basketball

In basketball, the "three second rule" refers to the amount of time an offensive player can spend in the free throw lane. If a player is inside the lane for more than three seconds, it results in a turnover and the ball is given to the opposing team. This rule is designed to promote movement and flow within the game and prevent players from camping out in the paint for extended periods of time. Referees keep a close eye on this rule and often use their whistle to indicate a violation.
