Doesn't mean. Mathematically, C32 and C3 1 are not equal. C32 and C3 1 respectively represent two different numbers in the combination number, where C32 represents the combination number of two items selected from three items, and C3 1 represents the combination number of 1 item selected from three items. Therefore, C32=3, C3 1=3. In some programming languages, C32 and C3 1 can also be expressed as variable names, depending on the rules and definitions of the programming language.
