text: Print all possible ways to write N as sum of two or more positive integers | Function to print the values stored in vector arr ; Traverse the vector arr ; Recursive function to prdifferent ways in which N can be written as a sum of at 2 or more positive integers ; If n is zero then prthis ways of breaking numbers ; Start from previous element in the representation till n ; Include current element from representation ; Call function again with reduced sum ; Backtrack to remove current element from representation ; Driver Code ; Given sum N ; To store the representation of breaking N ; Function Call
