  3. Coin roll hunting - Wikipedia

    en.wikipedia.org/wiki/Coin_roll_hunting

    After 1968, coins were minted in very high numbers, making silver coins uncommon, plus the introduction of silver-rejecting bank machines took many silver coins out of circulation. This all made silver too hard to find for coin roll hunters, so they primarily searched for 1922-1964 nickels for their numismatic value and 1965-1981 Nickels for ...

    A piggy bank, circa 1970. Earthen pots used in Nepal as piggy banks. Piggy bank (sometimes penny bank or money box) is the traditional name of a coin container normally used by children. The piggy bank is known to collectors as a "still bank" as opposed to the "mechanical banks" popular in the early 20th century. These items are also often used ...

  5. Change-making problem - Wikipedia

    en.wikipedia.org/wiki/Change-making_problem

    Another example is attempting to make 40 US cents without nickels (denomination 25, 10, 1) with similar result — the greedy chooses seven coins (25, 10, and 5 × 1), but the optimal is four (4 × 10). A coin system is called "canonical" if the greedy algorithm always solves its change-making problem optimally. It is possible to test whether a ...

    en.wikipedia.org/wiki/Divide-and-conquer_algorithm

    The divide-and-conquer technique is the basis of efficient algorithms for many problems, such as sorting (e.g., quicksort, merge sort), multiplying large numbers (e.g., the Karatsuba algorithm), finding the closest pair of points, syntactic analysis (e.g., top-down parsers), and computing the discrete Fourier transform .

    Coin Master is a casual mobile game that incorporates mechanics from village building, slot machines, and social interaction. The game was developed by Tel Aviv, Israel-based company Moon Active.

  8. Greedy algorithm - Wikipedia

    en.wikipedia.org/wiki/Greedy_algorithm

    Greedy algorithms determine the minimum number of coins to give while making change. These are the steps most people would take to emulate a greedy algorithm to represent 36 cents using only coins with values {1, 5, 10, 20}. The coin of the highest value, less than the remaining change owed, is the local optimum.

  9. Pigeonhole sort - Wikipedia

    en.wikipedia.org/wiki/Pigeonhole_sort

    The difference between pigeonhole sort and counting sort is that in counting sort, the auxiliary array does not contain lists of input elements, only counts: 3: 1; 4: 0; 5: 2; 6: 0; 7: 0; 8: 1; For arrays where N is much larger than n, bucket sort is a generalization that is more efficient in space and time.
