G - Parity
PDF (English) Ranklist
Time Limit: 0.5 second(s) Memory Limit: 32 MB

Given an integer n, first we represent it in binary. Then we count the number of ones. We say n has odd parity if the number of one's is odd. Otherwise we say n has even parity. 21 = (10101)2 has odd parity since the number of one's is 3. 6 = (110)2 has even parity.

Now you are given n, we have to say whether n has even or odd parity.


Input starts with an integer T (≤ 1000), denoting the number of test cases.

Each case contains an integer n (1 ≤ n < 231).


For each case, print the case number and 'odd' if n has odd parity, otherwise print 'even'.
