Alice goes for jogging every day for N meters. Sometimes she runs and sometimes she walks. Her walking speed is 1m/s and running speed is 2m/s . Given the distance up to which she does jogging, calculate the number of ways she can do jogging. example: Input: 3 (total distance covered during jogging) Output: 3…

Sticky index reference while inserting into 2D list in Python
While attempting to implement a function that produces all permutations given a list of integers, I’m seeing this behavior where the inserts are not occurring as expected. My code: When calling permute([1, 2, 3]) I’m expecting the perms to grow like: However, by the second iteration of the interio…
How to skim itertools permutations?
Initial code: Result: Now I want to remove everything starting with “)” or “#” and ends whit “(” or “#” and contenin “(“,”#”,”)” With Now the list is half in size “9k chart from 20k”. ps: Now, how do i remove (R…
Too many combinations
Hi I’m trying to generate all possible combinations of workers to buildings. (let me explain my scenario): I’m playing MineColonies on minecraft. In this mod you have colonists whom can be assigned jobs at buildings. These workers have skills and a score assigned to them. (like Agility: 20, Streng…
Efficient reverse-factorization of a number given list of divisors
Given a number n and a list of divisors A, how can I efficiently find all the combinations of divisors that, when multiplied, yield to the number? e.g. Output: This is what I managed to do so far (code that I re-adapted from one of the many find-prime-factorization questions on stackoverflow): This code seems…
Find two numbers from a list that add up to a specific number
This is super bad and messy, I am new to this, please help me. Basically, I was trying to find two numbers from a list that add up to a target number. I have set up an example with lst = [2, 4, 6, 10] and a target value of target = 8. The answer in this example would be
Shuffle DataFrame rows
I have the following DataFrame: The DataFrame is read from a CSV file. All rows which have Type 1 are on top, followed by the rows with Type 2, followed by the rows with Type 3, etc. I would like to shuffle the order of the DataFrame’s rows so that all Type’s are mixed. A possible result could be:…
How do I generate permutations of length LEN given a list of N Items?
Note: I’m working in python on this. For example, given a list: I want to generate a list of lists with all possible 3-item combinations: The permutations should not use the same item twice in a permutation, but the order is important and represents distinct permutations that should be included, e.g., S…
Finding all possible permutations of a given string in python
I have a string. I want to generate all permutations from that string, by changing the order of characters in it. For example, say: what I want is a list like this, Currently I am iterating on the list cast of the string, picking 2 letters randomly and transposing them to form a new string, and adding it to s…
