The algorithm reorders the input array from left to right by finding consecutive (disjoint) sorted segments (called “runs” from hereon). If the run is too short, it is extended using insertion sort. The lengths of the generated runs are added to an array namedrunLen. Whenever a new run...
Download the partially implemented file lab3flags.c. Similar to lab2C.c, this program keeps on reading inputs using getchar until end of file is entered. It then outputs if each digits is present in the inputs or not. • Observe that by putting getchar in the loop header, we just ...
