It is known that,
Odd numbers are the number which end with 1, 3, 5, 7 and 9.
Given numbers,
1,0,3,4,5
Here, the number should be end with 1, 3 or 5.
Now, for smallest number, smallest digit should be kept on first place which is zero in our case. But a number cannot be start with 0.
So, we will start the number with 1 at first place and use the zero at second place.
In 1, 3, 5, the number 5 should be place at last which is largest to get the smallest odd number.
Now the remaining number 4 should be kept at 4th place while 3 come at 3rd place.
