Given a string containing digits from 2-9 inclusive, return all possible letter combinations that the number could represent.
A mapping of digit to letters is done just like they are arranged on a telephone keypad.
Looking for ways of making the code more consise and easily readable. Want to le...

I had a project with repetitive HTML, JS code blocks. There should be 10 fields with certain functionality that is somewhere repetitive. The two table fields with logic is already implemented, but I don't want to copy and paste code blocks. Some repetitions I was able to solve, but majority of th...
Given a m x n grid filled with non-negative numbers, find a path from top left to bottom right which minimizes the sum of all numbers along its path.
**Note: You can only move either down or right at any point in time.**
Example:
**Input:**
[
[1,3,1],
[1,5,1],
[4,2,1]
]
**Output**: 7

This is the K&R Exercise 1-14 of C. The exercise ask you to print a histogram of the frequencies of different characters in input. How can I improve my code? The main doubt is the part when I have to increase letters in the array.

//this question is quite similar to coin exchange problem just a little change.
Vova had a pretty weird sleeping schedule. There are h hours in a day. Vova will sleep exactly n times. The i-th time he will sleep exactly after a[i] or a[i]-1 hours from the time he woke up. ...
I need to create a method to debias biased bytes from the method get_raw_bytes(length) using von Neumann debiasing method. Here's my current code:
def get_debiased_bytes(length):
arr_debiased_bytes = []
debiased_byte = 0
bit_counter = 0
while len(arr_debiased_bytes) < length:

In order to implement an efficient AST visitor preserving the principle of locality, I implemented some reference counting mechanism in C++ with the following set of features:
All the newly allocated memory shall be stored in a contiguous allocation memory, so to preserve the principle of local...
I am trying to add an functionality to existing code, and it seems like for this particular use case I should use Object Factory design pattern. However, would love to see your comments and may be better solution.

I'm implementing a std::function like class that uses type erasure.
So far it can be used with function objects (functions/function pointers, functors, lamdas) and pointer to member function.
But to support pointer to member function I used a C++17 feature, namely constexpr if, to choose at comp...
I need a code review because I have got no idea why this code is not working as it should.
Goals:
1)Require from user two strings until the first is not going to have equal number of vowels as second consonants.
2)Take the second word and replace every vowel in it with consecutive consonants from...
I made a code that adds 2 vectors that represent very large numbers (30k digits) but it is too slow. I am not sure how to make compiler vectorizes it or how to improve it. Thanks!
