Initially, x=0 When loop executes for first time, value of x becomes 1 and i is 10 so the condition i%2==1 becomes false. Now, when loop executes 2nd time, Value of i is i-x = 9 and x gets incremented. Now the condition i%2==1 becomes true and hence, loop breaks. Here, since value of x becomes 2(post increment), 2 is printed. Therefore, output is 2.

Let's start i=10 and i>0 is true so the loop will be executed, now x++ and then the if condition fails because 10%2 is equal to 0 and not to 1, now i=i-x is executed which is i=10-1 since x was incremented before. Now again 9>0 so we go into the loop, again x++ but now the if(i%2==1) is true since 9%2 is 1. So the break statement is executed and it comes out of the loop but remember x was already incremented before coming out of the loop. So it is 2 now. Hence the answer is 2.
