WebDec 21, 2024 · Maximum circular sum is 31. Complexity Analysis: Time Complexity: O(n), where n is the number of elements in the input array. As only linear traversal of the array is needed. Auxiliary Space: O(1). As no extra space is required. Note that the above algorithm doesn’t work if all numbers are negative, e.g., {-1, -2, -3}. It returns 0 in this case. WebApr 1, 2014 · 4. The formula of circle is. (x-a)^2 + (y-b)^2 - r^2 = 0. where x,y are coodrinates of point, a,b are coordinates of center and r is the circle radius. Just find all points for which this equation is true. Since your field is integer, you will need to replace =0 with <1 or even <= 1 whatever looks best. Share.
