Sir, upper bound will return the next highest element so if you apply for zero then it should give 10 not 20 please tell , this point is not clear .

[@sathishkumar-dc9ce]

Hi Krish, we will be storing the end value as key and start value as value, so upper bound of 0 will be 20. When we check our condition , i,e start=0, end = 5 and map has mp[20]=10 now upper_bound(start) is 20 and end

[@krishkumar491]

@@sathishkumar-dc9ce Mean the upper bound will be key in every comparison then we will compare the value i.e start point with the end.

[@techdose4u]

yes, because an interval can only start after any interval ends (0 or more)
