Problem 62. Elapsed Time Created by Cody Team in Cody Challenge Given two date strings d1 and d2 of the form yyyy/mm/dd HH:MM:SS (assume hours HH is in 24 hour mode), determine how much time, in decimal hours, separates them. Assume d2 is always later than d1. Example: Input d1 = '2010/12/14 12:00:00' Input d2 = '2010/12/14 13:06:36' Output elapsed is 1.11

Problem 15. Find the longest sequence of 1's in a binary sequence. Created by Cody Team in Cody Challenge Given a string such as s = '011110010000000100010111' find the length of the longest string of consecutive 1's. In this example, the answer would be 4. Example: Input x = '110100111' Output y is 3

Problem 76. De-dupe Created by Cody Team in Cody Challenge Remove all the redundant elements in a vector, but keep the first occurrence of each value in its original location. So if a = [5 3 6 4 7 7 3 5 9] then dedupe(a) = [5 3 6 4 7 9]

Problem 48. Making change Created by Cody Team in Cody Challenge Given an amount of currency, return a vector of this form: [100 50 20 10 5 2 1 0.5 0.25 0.1 0.05 0.01] Example: Input a = 257.68 Output b is [2 1 0 0 1 1 0 1 0 1 1 3] Always use bigger bills/coins if possible.

Problem 74. Balanced number Created by Cody Team in Cody Challenge Given a positive integer find whether it is a balanced number. For a balanced number the sum of first half of digits is equal to the second half. Examples: Input n = 13722 Output tf is true because 1 3 = 2 2. Input n = 23567414 Output tf = true All palindrome numbers are balanced. This is partly from Project Euler, Problem 217.

Problem 147. Too mean-spirited Created by the cyclist in Community Find the mean of each consecutive pair of numbers in the input row vector. For example, x=[1 2 3] ----> y = [1.5 2.5] x=[100 0 0 0 100] ----> y = [50 0 0 50]

Problem 174. Roll the Dice! Created by @bmtran (Bryant Tran) in Community Description Return two random integers between 1 and 6, inclusive, to simulate rolling 2 dice. Example [x1,x2] = rollDice(); x1 = 5; x2 = 2;

Problem 41. Cell joiner Created by Cody Team in Cody Challenge You are given a cell array of strings and a string delimiter. You need to produce one string which is composed of each string from the cell array separated by the delimiter. For example, this input in_cell = {'Lorem', 'ipsum', 'dolor', 'sit', 'amet', 'consectetur'}; delim = ' '; should produce this output: out_str = 'Lorem ipsum dolor sit amet consectetur';
