PROBLEM : Given a string str your task is to complete the function printSpaceString which takes only one argument the string str and  prints all possible strings that can be made by placing spaces (zero or one) in between them. For eg .  for the string abc all valid strings will be                 abc                 ab c                 a bc                 a b c Input: The First line of input takes an integer T denoting the number of test cases . Then T test cases follow . Each line of test case contains a string str . Output: For each test case output the strings possible in a single line  separated by a "$" Constraints: 1<=T<=100 1<=length of string str <=100 Example: Input 1 abc Output abc$ab c$a bc$a b c$ -------------------------------------------------------------------------------- SIMPLE c++ IMPLEMENTATION : -------------------------------------------------------------------------------- /* Please note that it's Fun

PROBLEM : Given a number your task is to complete the function convertFive which replace all zeros in the number with 5 and returns the number. Input: The first line of input contains an integer T denoting the number of test cases . Then T test cases follow . Each test case contains a single integer N denoting the number. Output: The output of the function will be an integer where all zero's are converted to 5 . Constraints: 1<=T<100 1<=N<=10000 Example: Input 2 1004 121 Ouput 1554 121 -------------------------------------------------------------------------------- SIMPLE c++ IMPLEMENTATION : -------------------------------------------------------------------------------- /* Please note that it's Function problem i.e. you need to write your solution in the form of Function(s) only. Driver Code to call/invoke your function would be added by GfG's Online Judge.*/ /*you are required to complete this method*/ int convertFive(int
