For finding the minimum:


  1. Create a variable, set it to the value of the first number.
  2. Compare that variable to the next number in the list. If it's larger set the variable to the value of the other variable.
  3. If you're not at the end of the list, go to step 2.
  4. Print the variable, which holds the smallest number.


Assuming an array with 5 numbers: [3, 4, 1, 2, 9]

code:
foo = 3
foo > 4?  No.  foo = 3
foo > 1? Yes.  foo = 1
foo > 2? No.  foo = 1
foo > 9? No.  foo = 1
1 is the smallest number
