 Problem Statement When data is transmitted over network, it is important to check its validity on the receiving side. This would ensure that data is not altered or corrupted. One of the known approach for validity check is to suffix the data with additional details generated from original data itself. As original data is always characters, it can be represented as number sequence (ASCII / UTF 8 etc). Hence, data like - ABCDcan be represented as 65666768referring ASCII codes. Hence, some additional data generated out of 65666768 can be suffixed while transmitting this sequence. One of the similar approach can be to build a logic where given number sequence is separated by certain digits each. Next, it is identified how many prime numbers are there in those separated numbers. Next, add this total number of prime numbers with second largest prime number in the separated sequence. This new number can be suffixed with #. E.g, if we want to to transmit the number sequence - 122423314766053.
