Losing to My Substitute (Katerina and Joshu) novel Chapter 69

Chapter 40 

Miss Emma, just like her mother, was dutiful. When the clock struck the hour, she would certainly 

knock on the door to remind Linda to take her medicine. 

And in doing so, she would be the first to discover that Linda had already left.

The voice was soft, like a lover’s whisper, carrying the quiet mysteries of youth. 

“It describes the asymptotic behavior of functions…” 

“Big O notation is a mathematical representation used to describe the asymptotic behavior of functions, particularly in algorithm analysis. It’s used to describe the running time or space **complexity of an algorithm, focusing on the growth rate of a function as the input size n becomes 

very large.”

The professor on the podium adjusted his glasses and nodded slowly. “I know developing programs after class is exhausting, but you still need to focus during lectures. Please take your seat.”
