No 100 is an all-out sprint.
It depends on the type of swimmer, though. Someone who is a great 200 breaststroker might save energy for the finish to catch the sprinters. Someone who is a sprinter might touch at the 50 one second over their actual 50 time.
But I know some sprinters who like to back-half their 100 ***. Again, it depends.
It's like asking how to swim a 100 free. Some might recommend swimming it like Roland Schoeman, who flips at the 50 less than a second over his actual 50. Others might recommend swimming it like Ian Thorpe, who can even-split the race and win an Olympic medal.
You need to experiment. Find the pace that suits you so you have energy to go all-out the final 20 yards/meters without excruciating pain.
