Please read the questions carefully and consider the sample solution provided at the end of my questions $,$ I Put it so you can run it and see how it should work $,$ you might need to fix only the expected output $,$ please note no entry input needed in the code $,$ just to have the expected outcome once I run it import jakarythrstaks:

You can write your main method so that it reads input from the keyboard $($standard input$)$ and outputs its results to the console $($standard output$)$ for testing. The first line of input should be the number of test cases to be executed. Subsequent input will be one chemical formula per line. For each formula, output the number of protons in the formula. Each output should be on a separate line. You do not need any additional prompts or output text.

Or you can use the formulas.txt file in the folder. Example input:

H

KBr

H$2$O

NaCl

C$6$H$12$O$6$

Example output:

$1$

$54$

$10$

This is an example of solution, however it give wrong output not matching the expected output of each chemical formula stated in at the beginning of the code $,$ please consider this however fix the output to the right expected one $,$ also please note there is no input entry no need $,$ I need to run and have the expected outcome with no input
