Oct 24, 2020 · 2 You put 1 / 3 of the coins on each pan and keep the last 1 / 3 of the coins off the balance. If the coins balance, the bad coin is in the 1 / 3 that are off the balance. If the coins do not balance, the fake coin is in the light 1 / 3. Either way, the number of possibilities is divided by 3 each time you use the balance.. For every coin, we have 2 options, either we include it or exclude it so if we think in terms of binary, its 0 (exclude) or 1 (include). so for example, if we have 2 coins, options will be 00, 01, 10, and 11. so it's 2^2. for n coins, it will be 2^n. In all these options we will be checking whether that selection has made the change that is. Here is an algorithm: Take number of coins, n, as an input, along with their weight with fake one having different weight than the real ones. If only one coin is there then that will be the fake coin. If more than one coins are there then divide the coins into piles of A = ceiling (n/3), B=ceiling (n/3), and C= n-2* ceiling (n/3)..
