WebMar 7, 2024 · Video. Given two positive integers n and k. The problem is to check whether the bit at position k from the right in the binary representation of n is set (‘1’) or unset (‘0’). Constraints: 1 <= k <= number of bits in the binary representation of n. Examples: Input : n = 10, k = 2 Output : Set (10)10 = (10 1 0) 2 The 2nd bit from the ... WebJun 17, 2024 · Output: Check the number has even parity or odd parity.

WebThe numbers behind the 'bars/underscores' are the parity-check bits, it means that in each column/row is even count of number 1. So the minimum distance equals to 2. That means according to the rule t < d, that this code can detect only a t-bit error, which means 1 ( but that's not true, because it can detect 3 bit erros).
