The paper presents a hexagonal 12-element array working at 5.8 GHz. The proposed device operates in circular polarization exploiting the sequential rotation architecture. The antenna elements are disc ...

// There is an integer array nums sorted in ascending order (with distinct values).

* (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). * You are given a target value to search. If found in the array return its * index, otherwise return -1. * You may assume no duplicate exists in ...

Costas arrays have ideal autocorrelation and are widely used in radar, sonar and other fields. Two main methods to obtain Costas arrays are algebraic construction and exhaustive search, the latter of ...

Use a sorted array if deletions and insertions are not going to happen often (or never). Otherwise a balanced binary search tree is usually more appropriate.
