WebMar 16, 2024 · Problem Statement: Among n identical looking coins, one is fake. With the help of a balance scale, we can compare any two sets of coins. That is, by tipping either to the left or, to the right or, staying balanced, the balance scale will indicate whether the sets weigh the same or whether a particular set is heavier than the other. 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.
