【题目描述】 Given an array S of n integers, are there elements a, b, c, and d in S such that a + b + c +
Sumin programming contexts is the process of adding together elements. These elements can be numbers, but depending on the programming language, can also include other data types as long as there's a clear definition of what addition means for those types. In higher-level programming languages li...
