A **restricted sumset** is a concept used in additive combinatorics, a branch of mathematics that studies various properties of sets of numbers, particularly in relation to addition. Given two sets \\(A\\) and \\(B\\) of integers, the **sumset** \\(A + B\\) is defined as the set of all possible sums obtained by taking one element from \\(A\\) and one element from \\(B\\).
