Exercise

Build a for loop from scratch

This exercise will not introduce any new concepts on for loops.

In the editor on the right, we already went ahead and defined a variable rquote. This variable has been split up into a vector that contains separate letters and has been stored in a vector chars with the strsplit() function.

Can you write code that counts the number of r's that come before the first u in rquote?

Initialize the variable rcount, as 0.
Finish the for loop:
if char equals "r", increase the value of rcount by 1.
if char equals "u", leave the for loop entirely with a break.
Finally, print out the variable rcount to the console to see if your code is correct.
