Given an array of integers a
and integers t
and x
, count how many elements in the array you can make equal to t
by increasing / decreasing it by x
(or doing nothing).
EASY!
# ex 1
a = [11, 5, 3]
t = 7
x = 2
count(a, t, x) # => 3
- you can make 11 equal to 7 by subtracting 2 twice
- you can make 5 equal to 7 by adding 2
- you can make 3 equal to 7 by adding 2 twice
# ex 2
a = [-4,6,8]
t = -7
x = -3
count(a, t, x) # => 2
-1018 <= a[i],t,x <= 1018
3 <= |a| <= 104
