Doubt in compare()?

#1

In compare(), we used return a<=b,
acc to this the lower_bound() should return the value either equal to key or just smaller than the key i.e if key=120, we should either get 120 or 100, but if we do so, in both cases we’ll get 200.

#2

hi @amandeepdogra65 lower_bound() using this compare function, will return the value that is strictly greater than the key.

#3

Can you explain how a<=b changes the behaviour?

#4

@amandeepdogra65 it will return the value that returns false for the comparison a <= b
