# 数据结构与算法 vs Data Structures and Algorithms

The clearest difference is ads: Data Structures and Algorithms at none against 数据结构与算法's shown. 数据结构与算法's advantage is iOS requirement (9.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 数据结构与算法 sells 2 one-off in-app purchases and Data Structures and Algorithms sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
