Wall of Sound but Phil came along and took these to make sounds that had not been used in the past. I thought it was ingenious." During the mid-1950s, Spector worked with Brill Building songwriters Jerry Leiber and Mike Stoller during a period where they sought a fuller sound by the use of excessive instrumentation, using up to five electric guitars and four percussionists. This was later to evolve into Spector's Wall of Sound, which Leiber and Stoller consider to be very distinct from what they were doing, stating: "Phil was the first one to use multiple drum kits, three pianos and so
Pairing heap Pairing heap A pairing heap is a type of heap data structure with relatively simple implementation and excellent practical amortized performance, introduced by Michael Fredman, Robert Sedgewick, Daniel Sleator, and Robert Tarjan in 1986. Pairing heaps are heap-ordered multiway tree structures, and can be considered simplified Fibonacci heaps. They are considered a "robust choice" for implementing such algorithms as Prim's MST algorithm, and support the following operations (assuming a min-heap): The analysis of pairing heaps' time complexity was initially inspired by that of splay trees. The amortized time per "delete-min" is , and the operations "find-min", "merge", and "insert" run
