1 .Selection of MPCS exams include a fitness test which is conducted on ground. There will be a batch of 3 trainees, appearing for running test in track for 3 rounds. You need to record their oxygen level after every round. After trainee are finished with all rounds, calculate for each trainee his average oxygen level over the 3 rounds and select one with highest oxygen level as the most fit trainee. If more than one trainee attains the same highest average level, they all need to be selected.
Display the most fit trainee (or trainees) and the highest average oxygen level.
Note:
The oxygen value entered should not be accepted if it is not in the range between 1 and 100.
If the calculated maximum average oxygen value of trainees is below 70 then declare the trainees as unfit with meaningful message as “All trainees are unfit.
Average Oxygen Values should be rounded.
Example 1:INPUT VALUES
9592
95
92
90
92
90
92
90
OUTPUT VALUES
Trainee Number : 1
Trainee Number : 3
Note:Input should be 9 integer values representing oxygen levels entered in order as
Round 1
Oxygen value of trainee 1
Oxygen value of trainee 2
Oxygen value of trainee 3
Round 2Oxygen value of trainee 1
Oxygen value of trainee 2
Oxygen value of trainee 3
Round 3Oxygen value of trainee 1
Oxygen value of trainee 2
Oxygen value of trainee 3
Output must be in given format as in above example. For any wrong input final output should display “INVALID INPUT”

2.Problem Statement
The Caesar cipher is a type of substitution cipher in which each alphabet in the plaintext or messages is shifted by a number of places down the alphabet.
For example,with a shift of 1, P would be replaced by Q, Q would become R, and so on.
To pass an encrypted message from one person to another, it is first necessary that both parties have the ‘Key’ for the cipher, so that the sender may encrypt and the receiver may decrypt it.
Key is the number of OFFSET to shift the cipher alphabet. Key can have basic shifts from 1 to 25 positions as there are 26 total alphabets.
As we are designing custom Caesar Cipher, in addition to alphabets, we are considering numeric digits from 0 to 9. Digits can also be shifted by key places.
For Example, if a given plain text contains any digit with values 5 and keyy =2, then 5 will be replaced by 7, “-”(minus sign) will remain as it is. Key value less than 0 should result into “INVALID INPUT”Example 1:
Enter your PlainText: All the best
Enter the Key: 1The encrypted Text is: Bmm uif Cftu
Write a function CustomCaesarCipher(int key, String message) which will accept plaintext and key as input parameters and returns its cipher text as output.
