How to add a empty space in particular index in string using regex

[sriramkukkadapu]

1) String s =

Write a logic to have only one '-' between words in above string (without using any temporary string)

o/p should be :
-My-Name-Is-XYZ-X-Y

2) Move all negative elements in an array to beginning (without using a temporary array, and preserve the order of -ve and +ve elements in the array)

int a[] = {1, 2, 3, 0, -1, 4, 5, -2, -3, 0, -7};
o/p should be
-1, -2, -3, -7, 1, 2, 3, 0, 4, 5, 0]

2nd one is really interesting
