Given a and b which both fit in 64-bit signed integers, find x=a/b where ⌊x⌋ denotes the largest integer whichis not larger than x.

The input contains zero or more test cases and is terminated by end-of-file. Each test case contains two integers a,b. • −2^63 ≤ a,b < 2^63 • b ̸=0 • The number of tests cases does not exceed 10^4.

For each case, output an integer which denotes the result.
