I am not able to understand the following

#1

elif(not(flag) and curr<prev):

What does not(flag) mean here? What is it doing?

#2

hey @prakhar.kamal.met17 ,
In the case you are refering too,
not is actually a not operation , mean it reverse the value of a boolean input , like True to False , or False to True.
So here if you consider flag =1
not(flag) will first convert it to boolean means not(True) and then interpret its output as False.

I hope this helped.

And Sir what is its role overthere? Like why are we not using just a single condition in the third elif statement? Why are we using not(flag) and curr<prev together?

there is no such hardcore rule , that you need to implement in this way only.
Its just a method to solve this , if you have any other algorithm in your mind then you can use that.

For current, i will need to check the whole code once. I can’t tell you like this

Can you please check it once and clear my doubt please.:sweat_smile::sweat_smile:

share me the code link please.

here the flag is just used to check or continue the increasing sequence.
flag to set that , the last number recieved was a valid number and we can continue else , we need to break at that moment
