Fake coin problem algorithm

Webthe counterfeit coin problem under consideration this means that if n coins are left for inspection and x coins are placed in each pan, then exactly m =max{x,n−2x} (1) coins will be left for inspection after this weigh-ing. Thus, in the case depicted in Figure 1, exactly max{6,8}=8 coins will be left for inspection after the weighing. WebProblem Statement. You are given an array ‘sum’ which is the prefix sum of an array of coins ‘C’ where ‘C [i]’ is ‘1’ if the coin is real, or ‘0’ if the coin is fake. There is exactly one fake coin in the array. Return the index of the fake coin. Assume the array to be 0-indexed.
