$ and the $t $ all become singular points, and the other points on the path are not changed after the edges on the path are removed.In step 2, because each connected block must have an even number of odd points, you can always find the $u $ and $v $ that meet the requirements. Because there are no other singularity points in the middle of the path, the parity of the other points does not change, and the subsequent operation of the algorithm is not affected, and the $u $ with $v $ as the path en

After the completion of the test scores of students and the score of each single division and the total score is our teacher here must do the homework. In the WPS table, calculate the student total score using the SUM function, with the rank function to arrange the position, which is also known to every teacher. However, there are always some special circumstances in each exam students lack of examination. If we calculate the total score by the actual score and arrange it, it is obviously unfair
