--description--

The allowed disk movements between the rods exhibit a repetitive pattern occurring every three moves. For example, movements between rod A and rod C are allowed on the first, the fourth and the seventh move, where the remainder of the division between the move number and 3 is equal to 1.

Inside the previously created for loop, replace the existing print() call with an if statement that is triggered when (i + 1) % 3 == 1. Within this if statement, print f'Move {i + 1} allowed between {source} and {target}' using an f-string. Please, note that i + 1 is the move number since i is zero during the first iteration.

--hints--

You should have an if statement that should be executed when (i + 1) % 3 == 1.

({test: () => assert.match(code, /if\s+\(\s*i\s*\+\s*1\s*\)\s*%\s*3\s*==\s*1\s*:/)})

You should print the string f'Move {i + 1} allowed between {source} and {target}' using an f-string.

({test: () => assert.match(code, /print\s*\(\s*f('|")Move\s\{\s*i\s*\+\s*1\s*\}\sallowed\sbetween\s\{\s*source\s*\}\sand\s\{\s*target\s*\s*\}\1\s*\)/)})
