You may try this case now -

4

c h 1 2

c h 1 5

c f 1 10

c f 1 3

for c f 1 10 you are getting wrong answer , try it !

Since u are getting TLE for subtask 2 you may try mine brute force approach as i am also not good in Dp.
What I did is for eg. this case c f 1 10 , traverse from 1 to 10 and if you encounter character as ā€˜cā€™ then increment count of c and whenever u encounter ā€˜fā€™ increment count of cf as cf=cf+c because count of strings starting with c and ending at f will depend on count of ā€˜cā€™ always, hope u understand.

You are now missing a very basic case

cf

f c 1 2

h f 1 2

for h f 1 2 your code gives output in my system as 33 which is wrong, either their is problem in initialization of your variables.
