GMJ Coding Techniques on Even Felicitous Labeling for Three and Four Star Graphs

In this Study, we have discovered a method for encoding a secret message using the GMJ (Graph Message Jumbled) code and even felicitous labeling on Three star graph K_(1,τ_1 )∪K_(1,τ_2 )∪K_(1,τ_3 ) and the Four star graph K_(1,ω_1 )∪K_(1,ω_2 )∪K_(1,ω_3 ) ∪K_(1,ω_4 ) . We Provide two examples for each star graph and utilizing a python program to count the vowels in a given sentence, Perfect numbers, Armstrong numbers, Co-prime numbers, and each program for applying alphabetical approaches. A technique for labeling an even felicitous graph and flow chart is described for converting plaintext into cipher text (Picture coding).
