prev  |  next  |  chance

Given a String, find any digits in the String and combine them to make a single number, in the order that they are encountered from RIGHT to LEFT - that is, in REVERSE ORDER. If there are no digits in the String, just return zero.


combineDigitsReverse("abc1def2ghi3jklm") → 321
combineDigitsReverse("hello45goodbye78") → 8754
combineDigitsReverse("1green0blue53red8purple") → 83501

...Save, Compile, Run (ctrl-enter)

public int combineDigitsReverse(String str) { }
