C++ program to find two points from two lines who are not same

Suppose we have two ranges (l1, r1), (l2, r2) represents two lines on x-axis. l1

So, if the input is like l1 = 2; r1 = 6; l2 = 3; r2 = 4, then the output will be a = 3, b = 4, other answers are also possible.

Steps

To solve this, we will follow these steps −

if l1 is same as l2, then:
   (increase l1 by 1)
return l1 and l2

Example

Let us see the following implementation to get better understanding −

#include 
using namespace std;

void solve(int l1, int r1, int l2, int r2) {
   if (l1 == l2)
      l1++;
   cout 
Input
2, 6, 3, 4
Output
2, 3
