weixuanhu b6c3fa8992 Interpolation search - fix endless loop bug, divide 0 bug and update description (#793)
* fix endless loop bug, divide 0 bug and update description

fix an endless bug, for example, if collection = [10,30,40,45,50,66,77,93], item = 67.

fix divide 0 bug,  when right=left it is not OK to point = left + ((item - sorted_collection[left]) * (right - left)) // (sorted_collection[right] - sorted_collection[left])

update 'sorted' to 'ascending sorted' in description to avoid confusion

* delete swap files

* delete 'address' and add input validation

Julien Castiaux 36828b106f [FIX] maths/PrimeCheck (#796)
Current implementation is buggy and hard to read.

* Negative values were raising a TypeError due to `math.sqrt`
* 1 was considered prime, it is not.
* 2 was considered not prime, it is.

The implementation has been corrected to fix the bugs and to enhance
readability.

A docstring has been added with the definition of a prime number.

A complete test suite has been written, it tests the 10 first primes, a
negative value, 0, 1 and some not prime numbers.

closes #795

Viraat Das 2fc2ae3f32 Created a generalized algo to edmonds karp (#724)
Edmonds Karp algorithm is traditionally with only one source and one sink. What do you do if you have multiple sources and sinks? This algorithm is a generalized algorithm that regardless of however many sinks and sources you have, will allow you to use this algorithm. It does this by using the traditional algorithm but adding an artificial source and sink that allows with "infinite" weight.
