Rake-and-scrape Rake-and-scrape Rake-and-scrape is a genre of music native to the Bahamas. Its main instruments are associated with the Goombay drum, Accordion also known as a Concertina, and a Hand saw. In 1886 an article in the Nassau Guardian mentions the usage of the Banjo, Drums, Concertina and other instruments during a celebration by Black Bahamians. The Concertina is also referenced to be in use in Nassau by Black Bahamians by William Drysdale in his book "In sunny lands: out-door life in Nassau and Cuba pg 29" written in the early 1880's. William Drysdale writes "They were three of a kind
Bubble sort allows us to skip over a lot of the elements, resulting in about a worst case 50% improvement in comparison count (though no improvement in swap counts), and adds very little complexity because the new code subsumes the "swapped" variable: To accomplish this in pseudocode we write the following: Alternate modifications, such as the cocktail shaker sort attempt to improve on the bubble sort performance while keeping the same idea of repeatedly comparing and swapping adjacent items. Although bubble sort is one of the simplest sorting algorithms to understand and implement, its "O"("n") complexity means that its efficiency decreases dramatically
