Singaporean prime minister Lee Hsien Loong has decided to reveal the source code of the Sudoku-solving app he personally coded.

The PM revealed he likes to program in his spare time last month and mentioned the Sudoku-solver. He's since taken to Facebook to announce the source code dump.

“The program is pretty basic,' the PM writes, “it runs at the command prompt, in a DOS window. Type in the data line by line (e.g. 1-3-8---6), then the solver will print out the solution (or all the solutions if there are several), the number of steps the program took searching for the solution, plus some search statistics.”

“Hope you have fun playing with this,” he adds. “Please tell me if you find any bugs!”

With the United Kingdom going to the polls this week, plenty of Reg readers will doubtless wish that the main candidates for prime minister – David Cameron and Ed Miliband – could code a single line of anything, never mind engage with the nation's technology community. Or maybe you'd prefer they, and Hsien Loong, stick to their knitting? ®
