Please write a C function freqTrans(str) that identifies and prints the most frequent letter transition given a sequence of lower-case letters.if the frequency is the same,please print the smallest alphabetical order.For example
freqTrans("abababbbabbba")
will print
a->b,Frequency:4.
Hint : Lower-case letter ASCII is from 97 to 122.You may use functions in<ctype.h> and/or<string.h> if you'd like
