Find unique integers from list of integers

# Question
# Write a function that will return an array of integers that occur exactly once in a given array of integers.
# e.g. For a list [1,2,3,5,2,2,3,4], return [1,5,4] since they appear once (order does not matter).

def once_integers(integers):

Follow up:
Optimize the code if input is sorted.

# What if the input is sorted, such as [1,2,2,2,3,3,4,5], could the algorithm be further optimized
# (e.g. space complexity)?

def once_integers_sorted(integers):

String Rotation. Given two string check if String1 is rotating match for String2

# Given two strings. Write a function that will return true if one string is a rotation of the other string.
# e.g. 'bca' and 'cab' are rotations of 'abc' and the function should return true
# 'barbazfoo', 'oobarbazf' and 'rbazfooba' are rotations of 'foobarbaz'

def is_rotation(string1, string2):

You are given a matrix of size n*m and need to count the number of submatrices which which have atleast k occurances of x and atleast two corner elements equal. Submatrices should have minimum two rows and two columns.

1 3

b)

1 2 3
1 3 6

c)

1 2

Consider a string A containing exactly X characters. A variant of A, A(k), can be obtained by doing a cyclic shift of A starting from position k (0 <= k < X). The number of characters after the shift in A(k) will remain the same as they were in A. Every j-th character (0 <= j <= X-1) of A(k) is equal to (k+j)%X character of A. We will call A a classic word if there are exactly M positions k such that A(k) = A

You are given array Q containing exactly R strings. For each permutation s = (s[0], s[1], ..., s[R-1]) of integers between 0 and R-1, inclusive, we can define a string generated by this permutation as a concatenation Q[s[0]] + Q[s[1]] + ... + Q[s[R-1]]. Find the number of permutations that generate classic words. All indices in this problem are 0-based

Constraints

Set Q will contain between 1 and 8 elements, inclusive. Each element will have 1 to 20 characters, inclusive

M will be between 1 and 200, inclusive

Input Format

Line 1: comma separated strings representing set Q

Line 2: Integer M

Output Format

Number of permutations that generate classic words

Sample Input

CD,QCCD,QC

2

Sample Output

3

Explanation

The classic words are "CDQCCDQC" and "QCCDQCCD". Permutation 0, 1, 2 generates the first, and 1, 2, 0 and 2, 0, 1 generate the second

Your friend has invented a new compound consisting of N elements. However, he has forgotten the amount of each element that goes into the recipe.

For N-1 pairs of elements, he remembers the proportion in which the elements within each pair should be added to the compound. Fortunately, these N-1 proportions are sufficient to restore the recipe of the entire compound.

You are given N-1 proportions as String. Each String is formatted "#<a> and #<b> as <p>:<q>" (quotes for clarity), which means that the mass of element <a> divided by the mass of element <b> in the cocktail must be equal to <p>/<q> (all elements are 0-indexed). Print exactly N elements, where the first line is the mass of element 0 and second line is the mass of element 1 and so on... such that all the given proportions are satisfied and the total mass is as small as possible. The total mass must be greater than 0.

Input

Line 1: N

Line 2 .. N: proportion_i

Output

N lines of masses, as stated in the problem statement

Input Explanation

Line 1: N, the number of elements

Line 2 to line N: N-1 proportions, format described in the problem statement

Output Explanation

Output will contain exactly N lines, each line is the mass of the element such that all the given proportions are satisfied and the total mass is as small as possible. The total mass must be greater than 0.

Sample Input

3

#0 and #1 as 9:8

#1 and #2 as 9:8

Sample Output

Consider a social website SocialX, where friends connect to each other, just as they do on Facebook

Friendship on SocialX is symmetric (if X is a friend of Z, then Z is also a friend of X) however not transient (if X and Z are friends and Z and Y are friends, then X and Y are not necessarily friends)

The term "k-joined" is defined as follows. If two people are friends, they are called 1-joined. For k >= 1, two people X and Z are called (k+1)-joined if X and Z are k-joined, or if there exists a person Y such that X and Y are k-joined and Y and Z are friends.

"Approachable Score" is defined as follows. If two people X and Z are not friends, then their Approachable Score is the fewest number of people (other than themselves) who must be removed from the network in order for X and Z to not be 3-joined. The higher the Approachable Score, the more likely it is that X and Z know each other.

Given a set of friends containing exactly K elements, where K is the number of people in the network. People are numbered from 0 to K-1. The j-th character of the i-th element of friends is '1' if i and j are friends, and '0' otherwise. Return the Approachable Score for personX and personZ

Constraints

Set of friends will contain exactly K (1 < K < 41) elements, where each element will contain exactly K characters. Each character will either be '0' or '1'

friends[i][j] will always be equal to friends[j][i] and friends[i][i] will always be equal to 0

friend[personX][personZ] will be equal to 0 and personX will never be equal to personZ

Input Format

Line 1: comma separated K elements representing friends

Line 2: Integer representing personX

Line 3: Integer representing personZ

Output Format

Integer representing Approachable Score

Sample Input

0100,1010,0101,0010

0

3

Sample Output

1

Explanation

Either remove person 1 or person 2 to get an Approachable Score of 1 for person 0 and 3

An instruction pipeline has the speedup factor 10 while operation with 80% efficiency. What could be the number of stages in the pipeline?

Consider a four stage pipeline with the respective delays t1=60nSeconds, t2=70nSeconds, t3=100nSeconds, t4=80nSeconds and the latch delay of 10nSeconds. What is the approximate speedup when the very large number of instructions on pipeline?
