It takes a string s as input and returns an integer, the number of characters in the string that are t or T. Please use a for loop to do the computation. I am banning the built-in function count for obvious reasons. It is good to understand how these basic functions are built. You could test the quality of your code using count before you submit, but be sure to remove those test calls when submitting! Fun fact: bad encryption algorithms may be broken using letter frequencies. Word frequencies are an interesting way to analyze the provenance of a piece of text (is it likely that Shakespeare wrote this
