Detecting the column of a key in a matrix can be done using two methods: masking and rotating the bits. Both methods are explained below.
Masking Method:
1. First, we need to create a mask that will help us isolate the bits in the column we are interested in. The mask will have a binary 1 in the position of the column we want to extract and binary 0s in all other positions.
2. We apply the mask to the matrix using the bitwise AND operation. This will set all bits in the matrix to 0 except for the ones in the column we want to extract.
3. We then check which column has non-zero bits using any method like counting the number of 1s in each column or using the bitwise OR operation on each column. The column with non-zero bits corresponds to the column of the key.
Rotating Method:
1. We need to rotate the bits of the matrix in such a way that the key appears in the first row.
2. We then check the first bit of each column to see if it is set or reset. If it is set, then the key is in that column. If it is reset, the key is not in that column.
3. If the first bit of all columns is reset, we need to rotate the matrix again in such a way that the second row becomes the first row, and repeat step 2 until we find the column with the key.
Both methods are effective in detecting the column of a key in a matrix. The choice of method depends on the specific problem and the available resources.
