For all integers n > 2, show that the number of integer
partitions of n in which each part is greater than one is given by
p(n)-p(n-1), where p(n) is the number of integer partitions of
n.
Partitions
Show that the number of partitions of an integer n into summands
of even size is equal to the number of partitions into summands
such that each summand occurs an even number of times.
Let N(n) be the number of all partitions of [n] with no
singleton blocks. And let A(n) be the number of all partitions of
[n] with at least one singleton block. Prove that for all n ≥ 1,
N(n+1) = A(n). Hint: try to give (even an informal) bijective
argument.
Statement:
For a given integer N, print all the squares of positive
integers where the square is less than or equal to N, in ascending
order.

Show that for any k ≥ 2, if n + 1 distinct integers are chosen
from the set [kn] = {1, 2, . . . , kn}, then there will be two
integers which differ by at most k − 1. Please demonstrate the
steps so that I can learn from it and solve other problems by
following the reasoning!
An integer n is said to be Pythagorean if there exist two
nonzero integers x and y such that x2 + y2 = n2 . Present an O(n)
time algorithm to check if a given integer n is Pythagorean or not.
Assume that you can nd the square root of any number in O(1)
time.
that, given an integer N and an integer K, returns the minimum
number of rounds that are necessary for John to leave the casino
with N chips, having played all-in no more than K times.
