Archana and Divya are two python programmers. Archana writes more lines of code than Divya per day. Divya being very enthusiastic person decided to improve on herself. Currently, Divya is ‘D’ problems behind Archana. So, Divya increased her speed to writing ‘K’ lines of code per day. Archana continue to write her code at ‘A’ lines of code per day. Write a python program to accept the three arguments i.e. D, K and A. and will return the number of days Divya will take to bypass Archana.
