Assuming this is referring to the Greensboro sit ins, it started a chain of sit ins at restaurants. The 4 African American college students were the first to challenge the segregation inside restaurants. They sat in at one, which led to others being inspired and joining in by sitting in at other restaurants.
Actually, the Allies adapted the strategy of island hopping in WWII because it saved lives, time, effort, money, ammunition, food, ships, and everything else. In taking only key islands, the other islands would be cut off from the Japanese mainland and basically all supplies and equipment. Island hopping also allowed the US to quickly go through the places without spending much time liberating each one. It help end the war sooner, and the US were able to complete their objective much more quickly.
hope this helps
