blocksToWall


A Block is composed of two enclosing X symbols, and - in between. The length of the Block denotes the number of - symbols. Thus, a block of length 3 is "X---X", and a Block of length 1 is "X-X". Write a function that accepts the number of blocks and their length as integers, and return a string representing them.


blocksToWall(1, 3) → "X---X"
blocksToWall(2, 1) → "X-XX-X"
blocksToWall(3, 0) → "XXXXXX"

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

public String blocksToWall(int blocks, int dashes) { }
