So okay the questions says..... "Define the function of two variables INDEX(C,S) as follows: The variables C can be any single character; S can be any character string. INDEX(C,S) is the position in string S of the first occurrence of the character C. If S does not contain the character C, the value of INDEX is 0." Let S = "MISSISSIPPI" and T= "BULLETIN". now it says find INDEX("I", S)??? am counting the letters of I then S... Someone please explain thanks.

          INDEX("I", S) = "the index of the first occurrence of "I" in string S"



          Since S = "MISSISSIPPI", we have INDEX("I", S) = 2.



          More examples:



          INDEX("S", S) = 3,

          INDEX("Z", S) = 0,

          INDEX("P", S) = 9.

          Para el género de plantas, véase Musa (planta). Apolo y la Nueve Musas En la mitología griega, las musas (en griego antiguo μοῦσαι « mousai» ) son, según los escritores más antiguos, las divinidades inspiradoras de las Artes: cada una de ellas está relacionada con ramas artísticas y del conocimiento. Son hijas de Zeus y de Mnemósine, compañeras del séquito de Apolo, dios olímpico de la música y patrón de las bellas artes, quien tuvo romances con cada una de ellas, dejando descendientes. Bajaban a la tierra a susurrar ideas e inspirar a aquellos mortales que las invocaran. En la época más arcaica eran las ninfas inspiradoras de las fuentes, en las cuales eran adoradas. Finalmente, alrededor de los siglos VIII-VII a. C. [ 1 ] ​ prevaleció en todo el territorio de la Hélade la adoración de las nueve Musas, que son Calíope, Clío, Erato, Euterpe, Melpómene, Polimnia, Talía, Terpsícore y Urania. El culto a las musas era originalmente de Tracia y Beocia, y fueron de vital impo...
