In the binary file and data management, endianness is the sequence of bytes of a digital data inside the computer memory.In computer memory there are two type of endian order, Big-endian system stores the most significant byte of the data.Small-endian systems store the least significant byte of the data.Read More

In this problem, we will understand the conversion of 2-D array to 1-D array. We will see how to store the elements of a 2-D array to a 1-D array.Here, the size of 1-D array is same as the total number of elements in 2-D array which is n*m.In programming ... Read More

Emirp number is a special type of number that is a prime number whose digits when reversed create another prime number (this prime number is different from the original one).Emirp is the reverse of prime. Some prime numbers that are not emirp are palindromic prime and single digit prime numbers. Some Emirp Numbers are ...
