Input The first line contains an integerT(1 ≤ T ≤ 100) specifying the number of test cases. The first line of each test case contains an integern(1 ≤ n ≤ 105), in whichnis the size of arraya. Then a line follows containingnintegersa1, ..., an(1 ≤...

Sort the array first. The negation rules are quite simple: execute negation for K times,so use a for loop after negation, if the next number (if has) is smaller, the next number is next to negation (if still in for loop). Here we use a greedy strategy. If the next number is non...

You are given two arrays aa and bb, both of length nn. Let's define a function f(l,r)=∑l≤i≤rai⋅bif(l,r)=∑l≤i≤rai⋅bi. Your task is to reorder the elements (choose an arbitrary order of elements) of the array bb to minimize the value of ∑1≤l≤r≤nf(l,r)∑...

The experimental validation of the beamforming technique applied to microphone array measurements is investigated in this paper. At first the method theoretical background is presented, highlighting the main parameters affecting its performances and studying their influence with the aim of producing an ins...
Following the alignment and protein-coding gene quantification of the GT and S samples, we observe a high overlap of called cells (i.e., barcodes) resulting from the Cellranger cell-calling algorithm (19,453 common barcodes, 166 barcodes unique to ground truth, 13 barcodes unique to the ...
implementation had the best performance on GPUs such as NVIDIA's GeForce 7 Series. Sengupta et al.'s implementation was used in a hierarchical shadow map algorithm to compact a stream of shadow pages, some of which required refinement and some of which did not, into a stream of only ...
