Course Items
While Loops
While loops are a type of programming structure that allows us to instruct the computer to repeatedly perform a command a set number of times.
Functional While Conditions
While loops are not always used to repeat an action a set number of times, rather it's better to think of them as having the ability to repeat an action until a certain condition is met.
String Algorithms 1
Of the material covered so far, Strings are the best resource we have for implementing iteration challenges. Here we'll take a moment to understand some String manipulation features.
For Loops
For loops are a shorthand for a while loop with an iterator
String Algorithms 2
Write a function that takes a string and capitalizes every other character.
Reverse
Write a function that uses a while loop to reverse a string.
Replace
Write a function to replace each instance of a letter in a string with a different letter
Contains
Write a function that checks if a given string contains a given substring.
Nested for loops
We can nest loops to repeat a set of repeated actions a certain number of times
Nested for loops challenge
Write a program to produce a checkerboard
