i messing around first question here: reduce duplicate characters desired minimum , looking more elegant answers came with. passes test curious see other solutions. sample tests are:
reducestring('aaaabbbb', 2) 'aabb' reducestring('xaaabbbb', 2) 'xaabb' reducestring('aaaabbbb', 1) 'ab' reducestring('aaxxxaabbbb', 2) 'aaxxaabb' and solution (that passes these tests):
reducestring = function(str, amount) { var count = 0; var result = ''; (var = 0; < str.length; i++) { if (str[i] === str[i+1]) { count++; if (count < amount) { result += str[i]; } } else { count = 0; result += str[i]; } }; return result; }
just use regular expressions.
var reducestring = function (str, amount) { var re = new regexp("(.)(?=\\1{" + amount + "})","g"); return str.replace(re, ""); }
