If you like math, this is the best advice. I did math with a CS minor, had a great time in college, and I seem to go in the same pool as people with a CS degree for hiring on any team I would actually want to work with. It also opens up a different set of backup plans or potential career switches if you don't want to or can't stay in software long term.

Further to this point, it's quite common to favour a candidate with a strong STEM degree who has learned to code as an adjacency.
