How to Use the Subset Calculator
- Enter the elements of your set in the input field, separated by commas. For example:
A, B, C, D
- Click the "Calculate" button to generate all possible subsets and display the total number of subsets.
- The calculator will show all subsets, each on a new line, and also display the total number of subsets (which is 2n where n is the number of elements in your set).
- Click "Reset" to clear all inputs and results.
Working Principle
A set with n elements has 2n possible subsets. This includes the empty set and the set itself. The calculator uses binary representation to generate all possible combinations of elements:
- For a set with 3 elements (A, B, C), there are 23 = 8 subsets
- Each subset corresponds to a binary number from 0 to 2n-1
- If a bit in the binary representation is 1, the corresponding element is included in the subset
Example
For the set {A, B, C}
, the subsets are:
- {} (empty set)
- {A}
- {B}
- {C}
- {A, B}
- {A, C}
- {B, C}
- {A, B, C}
As shown, there are 8 subsets in total (23 = 8).
