Following is the partition function for quicksort, where we have used the leftmost number as a pivot. Assume that our array, ARR = {14, 8, 7, 38, 22, 15, 9}, which is 7 in size. What will be the array ARR after we apply "partition(A, 0,  6)"*           9, 15, 22, 38, 7, 8, 14       7, 8, 9, 14, 15, 22, 38       9, 8, 14, 7, 22, 15, 38       9, 8, 7, 14, 22, 15, 38       7, 9, 15, 22, 38, 14, 6       38, 22, 15, 14, 9, 8, 7

Write a java labguage program to use parallel arrays to save User ID and Password. Ask the user to enter the user ID and Passwords for 3 users Save the above information in two parallel arrays (using the same index for each user) After the input is completed, ask the user to enter any user ID and then ask the password for that ID. Confirm if the User ID and password match, if not ask the password

Write a procedure for encryption by rotating each plaintext byte different number of positions. For example, in the following array that represents the encryption key, each number indicates a left rotation: key BYTE 6, 4, 1, 2, 7, 5, 2, 4, 3, 6. Pass the pointer to the text string in EDX, the array size to ECX, a pointer to the key array in ESI, and the direction value (0 or 1) in EBX. Assume that the key array size is 10. Your procedure should loop through plain text and align the key to the first 10 bytes of the message. Rotate each plain text to the left (if the value in EBX is 0) or to the right (if the value in EBX is 1) by the amount in the key array: first byte by 6, second byte by 4 etc. Then align the key to the next 10 bytes until the whole message is encrypted. Write a program that tests the procedure by calling : one time with EBX = 0 (encrypting), then with EBX = 1 (decrypting). Print out the text three times: the original, then the encrypted, then the decrypted.
