1. You need to design function which will resolve the given string by replacing the variables with their values. The variable will be enclosed in specific delimiter.
   For eg b -> #a#src
   a -> data#c#
   c -> base

If input is hello#b# output should be -> hellodatabasesrc.
The variable name wont contain delimiter

2. Max possible transactions - you are given an array which has transaction amounts.Along with a initial total 'T' . if tx amount < 0 , you are making deposit, if tx amount is positive you are withdrawing.
   Once you reach a stage where you cant withdraw more you have to stop. Find max number of tx which can be done by you.
   eg arr = [-2 -3 4 1 132 ] T =0
   output - 4

arr = [ -2 5 1 3 2 -3 -1 4 1 ] T = 5
output - 5
