We have a sandglass that runs for $X$ seconds. The sand drops from the upper bulb at a rate of $1$ gram per second. That is, the upper bulb initially contains $X$ grams of sand.
How many grams of sand will the upper bulb contains after $t$ seconds?
The input is given from Standard Input in the following format:
Print the number of sand in the upper bulb after $t$ second.
$17$ out of the initial $100$ grams of sand will be consumed, resulting in $83$ grams.
All $48$ grams of sand will be gone, resulting in $0$ grams.
