29. implement Shift<T>

type Shift<T extends any[]> = T extends [any, ...infer Rest] ? Rest : [];type A = Shift<[1,2,3]>; // [2, 3]type B = Shift<[1]>; // []type C = Shift<[]>; // []

The Shift type takes in a tuple T and checks if the tuple contains at least one element (T extends [any, ...infer Rest]). If it does, it returns the rest of the elements using the infer keyword to capture the type of the remaining elements. If the tuple is empty or only contains one element, it returns an empty tuple using the built-in [] type.
