WebYou have to find positions of minimal and maximal elements for each of these arrays. The first line of the input contains integer T ( 1 ≤ T ≤ 1000) — number of arrays in the test. Thus, at the beginning, you program should read number T, and then it should solve the problem for T jury's arrays one by one. Then input for each array goes. WebAn element x∈ Pis maximal if there is no element y∈ P with y&gt;x. Clearly these concepts are different. Minimum and minimal elements are defined dually.
