( 1993 ) H Degenerate Matrix PROGRAMMING binary search math 2100

B'The determinant of a matrix 2 xe2 x80 x89 xc3 x97 xe2 x80 x892 is defined as follows: A matrix is called degenerate if its determinant is equal to zero. The norm ||A|| of a matrix A is defined as a maximum of absolute values of its elements. You are given a matrix . Consider any degenerate matrix B such that norm ||A xe2 x80 x89- xe2 x80 x89B|| is minimum possible. Determine ||A xe2 x80 x89- xe2 x80 x89B||. The first line contains two integers a and b (|a|, xe2 x80 x89|b| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109), the elements of the first row of matrix A. The second line contains two integers c and d (|c|, xe2 x80 x89|d| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109) the elements of the second row of matrix A. Output a single real number, the minimum possible value of ||A xe2 x80 x89- xe2 x80 x89B||. Your answer is considered to be correct if its absolute or relative error does not exceed 10 xe2 x80 x89- xe2 x80 x899. In the first sample matrix B is In the second sample matrix B is '...
