b=a+b-(a=b);

nice

it will not work because every integer is some ascii value and integer has no uppercase or lowercase

Map<Integer, Long> numsInMap = Arrays.stream(nums).boxed() .collect(Collectors.groupingBy(x -> x, Collectors.counting())); numsInMap.entrySet().forEach(x -> System.out.println(x.getKey() + " -> " + x.getValue())); for java 8

if (num == 1 || num == 0) { return 1; } else { return num * factorial(num - 1); }

love the logic and your videos
