Irish stepdance traditional step dance in Munster. This style is largely performed on the balls of the feet with toes pointed outwards. Competitive dancers are judged on posture, timing, rhythm and execution, which in practice means a rigid torso, rapid and intricate footwork, and legs and feet crossed over each other, with knees close together. Irish stepdances can be placed into two categories. Solo stepdances, which are danced by a single dancer, and group stepdances, which are coordinated with 2 or more dancers. "Reel", "slip jig", "hornpipe", and "jig" are all types of Irish stepdances and are also types of Irish traditional
Activity selection problem that |S'| > |S| in the case that multiple maximal solutions have equal sizes. The activity selection problem is notable in that using a greedy algorithm to find a solution will always result in an optimal solution. A pseudocode sketch of the iterative version of the algorithm and a proof of the optimality of its result are included below. Line 1: This algorithm is called "Greedy-Iterative-Activity-Selector", because it is first of all a greedy algorithm, and then it is iterative. There's also a recursive version of this greedy algorithm. Note that these arrays are indexed starting from 1 up to
