NO CODING: Assume you have 4 bit-strings from the set {0,1}10; i.e., each bit-string is 10 bits long. Now, you concatenate the bit-strings column-wise (vertically) and output a vector (or an array) of 10 hexadecimal elements. Find what is the nal output if you do XOR of all elements (with each other) of the vector. Hints: The result of the vertical concatenation should produce 10 bit-strings, each with a length of 4 bits. You will need to convert each 4-bits-long bit-string to a hexadecimal number to create the vector. The result of the nal output will be a 4-bit binary number which is equivalent to a single-digit hexadecimal number.
