Editing Community Data Science Course (Spring 2016)/Day 3 Coding Challenges

== Challenges ==

# Search for your own name. Are there both boys and girls that have your name? Is it more popular for one group than for the other?
## Hint: don't use a for loop for this one.
# What is the most common name for each gender? 
# What is the least common? 
# How often does the least common occur? (Does that bother you?)
# Are there more boys names or girls names? 
## What about that start with "a"? 
## For every letter, tell if there are more boys names or girls names.
# What is the longest name in the dataset?
# How many boys and girls are described in the dataset (i.e., how many boys and girls born in 2013 have names given to at least four others)?
# How many boys names are also girls names? How many girls names are also boys names?
# How many names are subsets of other names?
# Write a program that will take a name as input and return the number of girls and boys with that name.
# What is the most popular girls name that is also a boys name?
# Take a prefix as input and print the number of boys and girls with that prefix. (i.e., "m" would list babies whose names start with "m" and "ma" would list babies whose names start with "ma", etc).
# Discover at least one fact about the names that is not listed above.
# ''Challenge'' plot (in Excel) the number of people who share a name with n other people in the data set, where n is 4 to 19.

# Re-work anything above and make sure you are understand it
# Get the ratio of names that start with each letter.
## Do this for boys and girls.
## '''Hint''' First line of output is a boys: 0.10120456305133887 girls: 0.18231978026407467
# Are girls or boys more likely to have a name that is used by both genders?
