How can run native executables compiled for ARM on unrooted Android devices?

Following this tutorial I have compiled a Hello World! ARM binary from C source using gcc.
I want to run this program on my unrooted Android phone but I can't figure out an easy way to do it.

What I've tried:

1. Copying hello to /sdcard and trying to run it from there. This doesn't work because the internal storage is mounted with the noexec flag.




2. Copying hello to /data/local/ using cp hello /data/local/ or cat hello > /data/local/hello as explained here. This also doesn't work and I get a "permission denied" error.




3. Installing a terminal emulator program such as Termux and using the Termux app to copy hello from /sdcard/hello to /data/data/com.termux/files/home, running chmod +x hello and then running ./hello from the Termux home directory within the Termux app. This works but is not a feasible solution.

Is there a better/easier way to run native ELF executables on an unrooted Android phone directly through ADB and doesn't involve installing any apps?
