#### Category : subsequence

Source Code of Problem C++ Code for finding subsequence of a given string. In this problem I have used recursion for solving this problem. I also get the correct approach of this problem and code it also. But now my code is not working. It is giving a runtime error when I input a string. ..

#include <bits/stdc++.h> using namespace std; void printSubsequence(string input, string output) { if (input.empty()) { cout << output << endl; return; } printSubsequence(input.substr(1), output + input); printSubsequence(input.substr(1), output); } int main() { string output = ""; string input = "abcd"; printSubsequence(input, output); return 0; } Here, the function printSubsequence() is called twice in the function itself. ..

Two strings are given A and B . A.size() >= B.size() . We have to find minimum number of elements to remove from A .such that A is not subsequence of B Source: Windows Que..

How do i find all subsequences whose sum lies between a to b efficiently? I tried the general method of first creating subsequences and then checking the condition if it exists between a and b or not. Here’s my try. can i also optimize it? in case i dont want them printed.(as in case of ..

How do i find all subsequences whose sum lies between a to b. I tried the general method of first creating subsequences and then checking the condition if it exists between a and b or not. Here’s my try . can i also optimize it ; (i dont know dp ) #include <bits/stdc++.h> using namespace ..

Is there a way to return a distance between the first iterator of a sequence, which yields the start of a subsequence in case it is contained within the sequence? I know there is std::includes which returns true if a sequence is a subsequence of another. And it can take a Compare object. My first ..
