post pruning and pre pruning. Decision tree leads to overfitting hence requires pruning. Decsion tree is made using training data set so it may overfit because it wont perform optimally on test data set. Efficient is preprunning. Which is done in case of large dataset and postpruning can be done when small data set is used. Postpruning: first make the decision tree and then do the pruning(eg max depth , max features for split hyperparameter). Max depth me level define kar sakte ho starting from 0 till your depth. Basically acc to this hyperparameter you cant split beyond the specified depth. Prepruning: Apply all hyperparamters tuning along with making of decision tree. Decide max depth as range of values and max features also as a range of values.

Pre-pruning is not more efficient in terms of accuracy and fit. In terms of run time it is.
