Reverse String using Recursion C++

-

Here the Logic is simple to print the last character of the string for each function call and again call the reverse function again ,this time the string doesn't contain last character.


#include<bits/stdc++.h>

using namespace std;

void reve(string k)
{

  int sz=k.size();
  if(sz==1)
    cout<<k[sz-1];
  else
  {
     cout<<k[sz-1];
     string p=k.substr(0,sz-1);
     reve(p);
  }
}

int main()
{
    string s;
    cin>>s;
    reve(s);

    return 0;
}

Divide Intervals Into Minimum Number of Groups

  Divide Intervals Into Minimum Number of Groups  Leetcode Problem  Divide Intervals Into Minimum Number of Groups   is very much similar to the number-of-the-smallest-unoccupied-chair  Here we have to divide the given intervals into minimum number of groups such that each interval is in exactly one group, and no two intervals that are in the same group intersect each other. Solution: We will think each interval as combination of two events ,  startTime  and endTime. 1) We create a list of events and then sort that list.  2) After that, we Initialise a min heap. which can be thinked like different baskets or groups.  3) We iterate through the events one by one, and assign each events to groups (picked from minheap).      While iterating starting event we pick a group from min heap and keep track in an array.       While iterating ending event through our tracking array, we release the group again in min...
