What is the complexity of this function in the worst case? you will define the unit operations and parameter prior to compute the result

int canPay (int wallet), int start, int end, int amount) { if (amount == 0) return true; if (start > end) return false; if (canPay(wallet, start+1, end, amount-vallet[start] return true; return canPay (wallet, start+1, end, amount); What is the complexity of this function in the worst case? You will define the unit operation(s) and parameter prior to compute the result
