Recently I came across a good example in which we can see the power of dp so I thought why not make a video about it.
In the video, I tried to explain why we need dp by taking a simple example of hens and egg. Later on I calculated the nth element of the Fibonacci series using memorization.
fibonacci can be done faster
there's also a closed form (Binet's Formula)
Se da un sir de cifre separate prin operatori '*' sau '+'. Avand voie sa faci maxim K interschimbari intre operatori, aflati valoarea maxima a expresiei.
Am o problema mai calitativa.
Se da un sir de cifre separate prin operatori '*', '+', '-', '/', '^', '&', 'XOR', '!' '|'. Avand voie sa faci maxim K interschimbari intre operatori, aflati valoarea maxima a expresiei.

That's not the same problem.
You are wrong, it is Romanian TST Junior problem. (Which it in of itself means it is cleeaarly not reappearing on some lost cses page)
Also I forgot: number of digits is <= 1000 and number of '*' is <= 18.
