"strcpy() copies a string (null-terminated array of characters) from one location to another, while ensuring that the destination is allocated enough space to hold the entire source string. It automatically adds a null character at the end. memmove() or memcpy(), on the other hand, can copy a block of memory with any size and does not guarantee null termination of the copied data."

You have an array of n integers, randomly ordered with value 1 to n-1.The array is such that there is only one and one value occurred twice. How will you find this number?
