Or memoization.

It is a problem on your system then. It works fine elsewhere

Any solution for this? Thank you!

https://pastebin.com/cvuT7NV6 Can someone help me out in finding the error? It's the classical 0/1 knapsack, I implemented with memoization - the answer isn't getting displayed :/

Knapsack with repetitions?

Nope, simple one

Memset again with -1????

Memset again with -1????

BTW, I used memset on similar problems and it worked like a charm :/

Your DP equation looks fine too.

Your DP equation looks fine too.

okay it's working used memset itself btw xD

What was the issue

I had to use an additional space of n+1, W+1 since I was starting with 1 and the last index, that's the result would be at the dp[n][W]

Hey programmers so am new at c++ trying to do a basic calculator using classes and objects Wrote my program wanted to like bring results of a specific method if called upon like if addition is called it brings the results of addition buhh kinda stuck here seems like it can't compile from their 👇 #include <iostream> using namespace std; class Calculator { public: double sum,sub,mult,div,mod; int num1,num2; void Addition(),Subtraction(),Multiplication(),Division(),Modulas() { cout<<"Enter the first number:"<<endl; cin>>num1; cout<<"Enter the second number:"<<endl; cin>>num2; sum = num1+num2; sub = num1-num2; mult = num1*num2; div = num1/num2; } void results() { if(Addition){ cout<<"The Sum of the first and second number is"<<sum<<endl; } } }; int main() { return 0; }

is it possible the line, void addition(), subtraction() ..... { body } anyone?

if we want to keep the order of the elements as it is then we should use stable sort

stable_sort(begin(arr), end(arr), x{ return abs(a - x) < abs(b - x); }); can someone explain this what that [x] means here

I dont find [x] but i think I got your point, it is for lambda expressions, You must refer Lambda expressions in sorting algorithms on google, you will understand in better way. They allows us to perform the sort as we want, like odds should be come first or something else you wnnt.

hello this function can't run in my Ide it keeps showing wrong : fgets(name, 20 , stdin ) ;

#include <iostream> int main() { std::string input = "nitin"; unsigned inputLength = input.length(); for (unsigned i = 0; i < inputLength; i++) { for (unsigned j = i + 1; j <= inputLength; j++) { std::string subStringInput = input.substr(i, j); std::cout << subStringInput << std::endl; } } std::cin.get(); } Output: n ni nit niti nitin it iti itin itin tin tin tin in in n What is wrong in this code ? This does not print all the substrings of the string.

Anyone have best book of c++

Awesome! Can I dm you @tuxifan ?

pls review the code

Which is the best book for c++
