Question

This program works for reading a text of all upper case letters and it provides the  order of descending frequency. I need help modifying this exact program to do the  order of descending frequency of a text file that contains symbols,numbers,spaces,upper and lower letter.

>>>>>>>>>example of the text file being read is like<<<<<<<<<<<<<<

Z4XPsXZ|%%+%WZ<X%+|%Ry%|Z|%a|POR%ZLiZ<X%ZX%c<Z<XL*|caW|

For example in the current program I have the output text file give me, It's basically the same concept but I need it for a text file shown above^^
