So I gave my first CF round yesterday 913 (Div. 3) & I saw these lines
"It is guaranteed that the sum of n over all test cases does not exceed 2*10^5" or
"It is guaranteed that each line contains at least one letter and the sum of the lengths of the lines does not exceed 10^6"
I get it that they are probably trying to convey time limit but still exactly what do they mean (not the literal meaning)/how are they conveying that through that specific number.
