In a 1999 paper, Brodnik et al. describe a tiered dynamic array data construction, which wastes only n1/2 Place for n things at any level in time, plus they prove a reduced sure showing that any dynamic array will have to waste this much Room In case the functions are to remain amortized continuous time.
Dictionary may be used like an array to obtain its unique elements. Specify key (not index) to obtain a value from the dictionary working with indexer like an array. Illustration: Entry Unique Component
