Such as sort(), pop(), shift(), reverse()...

climbing has 13 fewer points than volcano, but it gets a higher scoring if you add, oh lets say 96 to the value of each letter. climbing has one more letter than volcano, so if you give points 96 extra points for each letter, the total score for climbing will be 83 greater than the total for volcano (96-13)

climbing = 69
c: 3, l: 12, i: 9, m: 13, b: 2, i: 9, n: 14, g: 7

volcano = 82
v: 22, o: 15, l: 12, c: 3, a: 1, n: 14, o: 15
