Key = ROYALNEWZEALANDNAVY. Initially we represent the given key in a 5x5 matrix form without repetition of letters. After that, we fill the matrix with remaining left over letters in A-Z in alphabetical order. Remember that I/J has to repsented in the same box.The matrix looks like:
Now we take two letters at a time and follow the below rules to decrpyt the given message:
1) If the same letter appears twice, represent the letter one time as it is. For example, TT will be decrypted as T.
2) If two letters appear on the same row, replace each letter by the letter which is immediately to the left of it.
3) If two letters appear on the same column, replace each letter by the letter which is immediately to the above of it.
4) Otherwise, form a rectangle for which the two letters are at two opposite corners. Then replace each letter with the letter that forms other corner of the rectangle in the same row.
Given code: KXJEY UREBE ZWEHE WRYTU HEYFS

Take two letters at a time and decrypt using the above rules.Take KX and check them in the matrix. We can see that they form a rectangle. So replace K and X with the letters that form the corners of the rectangle i.e P and T.
Now take J and E. We can see that J and E are located on the same column. So replace each letter with the letter that is immediately above it. Replace J with B and E with O.
Take Y and U. We can see that they are forming a rectangle. So replace them with letters that form other corners of the rectangle. Replace Y with A and U with T.
Take R and E. We can see that they are forming a rectangle. So replace them with letters that form other corners of the rectangle. Replace R with O and E with N.
Take B and E. We can see that B and E are located on the same column. So replace each letter with the letter that is immediately above it. Replace B with E and E with O.
Take Z and W. We can see that Z and W are located on the same row. So replace each letter with the letter that is immediately to the left of it. Replace Z with W and W with E.
Repeat the above process until all the letters are decrypted. Then form a meaningful sentence out of it. Therefore, the given message after decryption is:

The concatenate function takes in pointers to the head of both lists and iterates through the first list until it reaches the end. It then sets the next pointer of the last node in the first list to the head of the second list, effectively concatenating the two lists. The program then prints out the concatenated list.

Initially, the PC motherboard's ROM chip served as the location for the BIOS firmware. The BIOS data is saved on flash memory in more recent computers so that it may be changed without removing the chip from the motherboard. These settings were saved in nonvolatile RAM by the BIOS the last time the computer booted properly. The CMOS is where the BIOS saves the date, time, and system configuration information it needs to start the computer. The BIOS is the programme that initiates this process.
