Hi, Practice SRM's list is too big for 720p screens to access SRM's after 823. https://imgur.com/tFBqCx6

Current I'm flipping the screen to portrait mode to access SRM 824. https://imgur.com/Evb8iIP

Ok, the solutions were kinda uninspiring — 250 simple casework based on number of hidden pairs, 500 subtract 1 from the number with lowest set bit and show that the winner has to subtract 1 from another such number, 1000 show that there's a false after each true so sequences are FTFTFT... and for odd N also FFTFT..., FTFFTFT..., etc + implementation. But holy hell that challenge phase.
