Dear Codeforces community,

Today I realised I should teach more people the secrets on how to become a Master in Codeforces like 20llmc.

The key to reaching orange is to just acquire some 4-anilino-4'-nitroazobenzene and spread it all over your keyboard. This will ensure that you absorb the most orange powers while you type code. If you are going for Legendary Grandmaster, replace that with squid ink.

Regarding 4-anilino-4'-nitroazobenzene, this dye is useful in conducting experiments with flash photolysis due to the isomerization effect between the trans-4A4N and cis-4A4N states that occurs during photo relaxation. Hence, I believe it will have the maximum effect on helping you become a Master in Codeforces.

If you are too poor to buy / chemically synthesize it, then you are having a skill issue. An easy solution to this is to bake some lemon tart. The following is a procedure written in English (not C++, sorry in advance) on how to bake lemon tart:

Make the crust: in the bowl of a mixer, cream together butter and sugar. Add egg yolk and the milk, and beat to combine. In a medium bowl, combine the flour with salt. Slowly add the flour to the butter mixture, stirring until completely blended. Gather dough into two balls. Freeze one for future use, chill the other for at least 1 hour.

Heavily butter a 10-inch tart pan with a removable bottom. Press the dough into the pan and trim the edges. Prick the bottom with a fork, and place the shell in the freezer for 30 minutes.

While shell is in freezer, prepare lemon curd. Grate zest of lemons. Squeeze lemons to extract 1 cup of juice. In a medium nonreactive saucepan, combine juice and zest. Add remaining sugar, butter and salt. Place over medium heat, stirring once or twice, until sugar is dissolved and the butter is melted.

In bowl of a mixer, combine eggs and egg yolks until blended. Slowly add hot lemon mixture to eggs until blended. Return mixture to saucepan, and place over low heat. Whisk constantly until mixture thickens to a pudding-like consistency; do not allow it to boil. Remove from heat, and continue to stir to stop the cooking. Strain lemon curd into a bowl. Adjust sugar to taste; the curd should be tart, but may need additional sugar if the lemons were unripe. Cover with plastic wrap, pressing it right against the surface of the curd. Allow to cool.

Heat oven to 375 degrees. Remove tart shell from freezer, and bake until lightly golden, 20 to 25 minutes. Remove from heat and allow to cool slightly. Spoon lemon curd into tart shell, and smooth the top. Bake until filling has puffed around the edges, about 30 minutes. Cover edges with foil, if necessary, to prevent over-browning. Cool to room temperature before serving.

I hope you have a great time trying to become a Master, and I wish you all the success in the near future!
