The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/
A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by funcional category:
git status list which (unstaged) files have changed
| #Ruby | |
| #cuts array in half and nest in new array | |
| #can be kept as an Enumerator | |
| #useful for creating buckets for dynamic programming | |
| #useful for finding palidromes | |
| #arrays can be called individually using input[0] or input[1] | |
| def cut_in_half(input) | |
| input.each_cons(input.length/2).to_a | |
| end |
| #finds the largest product of two adjacent numbers in an array | |
| def adjacentElementsProduct(inputArray) | |
| inputArray.each_cons(2).map { |x, y| x*y }.max | |
| end |
| def largestNumber(n) | |
| new_array = Array.new(n, 9) | |
| new_array.join.to_i | |
| end |
| def add_digits(n) | |
| #maps characters of a string and converts it back to integers in an array | |
| sum = n.to_s.chars.map(&:to_i) | |
| #collapses the array by adding elements together. Same as inject. | |
| sum.reduce(:+) | |
| end | |
| def centuryFromYear(year) | |
| #solution requires us find out if the century has a remainder of 0 or not. | |
| #we can remove the remainder from the year to get a clean number since centuries happen in multiples of 100 | |
| if (year % 100) == 0 | |
| year/100 | |
| else | |
| (year - (year % 100))/100 + 1 | |
| end | |
| end |
