Dijkstra’s algorithm may not terminate if the graph contains negative-weight edges
a) false. it always terminates after |e| relaxations and |v|+|e| priority queue operations, but may produce incorrect results.
b) true. it may not terminate and if it does after |e| relaxations and |v|+|e| priority queue operations, it may produce incorrect results.
c) true. it can never terminate as the negative-weight edges continuously reduce the shortest path weight even after |e| relaxations and |v|+|e| priority queue operations.
d) false. it can surely terminate as long as the negative-weight edges are not considered for the shortest path weight calculation among those |e| relaxations and |v|+|e| priority queue operations

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
