Pretend you are a machine executing the code provided below, in the exact order that a machine would execute it. Assume the variables have the following values before starting: x = 1, y = 3. Track the use of the variable named y. Every time the variable is used as a left value (i.e. changed in memory), note (eg. write it on paper) the new value. Every time the variable is used as a right value (i.e. read from memory), note the (old) value. To provide an answer construct a string containing only digits and no spaces or other symbols, from the values you have written down, in that exact order.

for( ; 1; ) if (y < x++) break;
