S) suppose we are given a sequence s of n elements, each of which is colored blue or gold. assuming s is represented as an array, give an algorithm for ordering s so that all the blue elements are listed before all the red elements. you may allocate o(1) additional space for doing so. your running time must be o(n) for full credit.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
