ALL--A Little Language for Teaching Algorithms and Data Structures
ALL——算法与数据结构教学小语言

Based on the idea of domain-specific languages,a little language-ALL is proposed as a response to some problems in teaching "Algorithms and Data Structures". We expect that ALL will help decouple the learning of algorithms and data structures from the learning of programming languages. The definition and implementation of the main elements of ALL are introduced in this paper.
