uncheatable random number generator from 1 to 100

easy way:
 just pick a random number from 1 to 100 (but this method can be cheated)
write L=the number you picked on the variables paper

hard way:
uncheatable random number generator from 1 to 100
you need 2 players to play this game, the “player” and the “executor”
the executor does everything except where it is mentioned that the player should do something.

how to get a number from 0 to 50
Random_Number_0_to_50:
repeat until the result is not negative:
-roll first dice multiply times 10 then add the second roll of dice
-subtract 11
-the player should write down the results of both dice rolls and save them for later
-the executor should write down the hidden random number  and keep it hidden until the game is over
-be sure to record every pair of rolls of the dice and every hidden number for later verification

how to get a number 0 to 100
RandomNumberA is Random_Number_0_to_50
RandomNumberB is Random_Number_0_to_50
if RandomNumberB is 0 then change RandomNumberB to 1
make Random_number_Zero_to_100 into  RandomNumberA+RandomNumberB
write down L=Random_number_Zero_to_100 on the variables paper

after the game ends:
repeat for every pair of rolls of the dice:
repeat until the result is not negative:
-first roll of dice written down by player multiply times 10 then add the second roll of dice
-subtract 11
if the number is equal to the hidden random number then the executor did not cheat, otherwise he cheated
