What is <===> in line 17? Is it operator or something else and also tell me its work here? I have searched it online but did not get the answer.
It’s just a style figure to help human eyes see what’s going on better. It’s not computed, just rendered as a string. Same as <----->. Or you could equally do <===================> and your eyes would see it as 2 joined arrows.
I got it. Thank you:slightly_smiling_face:
