Question 291746
suggestion :
Don't run your problems together like that.
It causes confusion  and errors.
Some website rules you won't like:
You are limited to one problem per submission. [One problem at a time.]
To be sure we understand each other, one means one not two or three or more.
No more than 4 submissions daily. [4 problems a day]
No similar problems. [Different type problems only.]
first is ok second is wrong. 
I would say more but the second problem shouldn't be there
