A sequence x is a subsequence of a sequence y if x can be obtained from y by deletion of several (possibly, zero or all) elements. Input The first line contains a single integer t ( 1 ≤ t ≤ 1000) — the number of test cases. The next 2 ⋅ t lines contain descriptions of test cases. The description of each test case consists of two lines. Time limit: 1.00 s Memory limit: 512 MB Your task is to find a minimum length bit string that has exactly $n$ distinct **subsequences**. For example, a correct solution. The first line contains 5 space-separated integers: n, k, p, x and y (1 ≤ n ≤ 999, n is odd, 0 ≤ k < n, 1 ≤ p ≤ 1000, n ≤ x ≤ n·p, 1 ≤ y ≤ p).Here n is the number of tests that Vova is planned to write, k is the number of tests he has already written, p is the maximum possible mark for a test, x is the maximum total number of points so that the classmates don't yet disturb. .Declare recursive.

For example, if our **subsequences** will be:. For each **subsequence**, we apply the bitwise XOR operation on all the integers and record the resultant value.Since there are **subsequences**, this will result in numbers.. Given array , find the XOR sum of every **subsequence** of and determine the frequency at which each number occurs. Then print the number and its respective frequency as two space-separated. levelCount = 1; allCount = 1; map = {a:1,b:-1} 2nd iteration 'b'. Distinct **Subsequences** ending with 'b' are "ab","b". So the levelCount = 2. Also total **subsequences** we found till now are 3. allCount = 3. Here we can notice that levelCount can be determined from last value of allCount variable by adding 1 to it. all nonempty **subsequences**. Print the two values as space-separated integers on one line. Note that empty subarrays/**subsequences** should not be considered. Example. The maximum subarray sum is comprised of elements at inidices . Their sum is . The maximum **subsequence** sum is comprised of elements at indices and their sum is . Function Description.

Dec 14, 2021 · Two **subsequences** are considered different if index sets of elements included in them are different.

A sequence x is a subsequence of a sequence y if x can be obtained from y by deletion of several (possibly, zero or all) elements. The average of a subsequence is the sum of the numbers of this subsequence divided by the size of the subsequence. For example, the average of [ 1, 5, 6] is ( 1 + 5 + 6) / 3 = 12 / 3 = 4, so f ( [ 1, 5, 6]) = 4. Input. Karl likes **Codeforces** and **subsequences**.
