Question: An algorithm sorts a set S of integers in Theta ( nlogn ) time and then uses a two - pointer technique to find

An algorithm sorts a set S of integers in \Theta (nlogn) time and then uses a two-pointer technique to find if any two elements sum to x. It's efficient due to the initial sorting and the linear search using pointers. If a pair is found that sums to x, it returns true; otherwise, false.
