    सबसे आसान तरीका क्या है क्या यह जावास्क्रिप्ट में है? वर्तमान में मेरा कोड एक विशाल स्विच ब्लॉक है, क्या कोई आसान तरीका है?

    वर्तमान कोड: 

      फ़ंक्शन कन्वर्टबिनोहेक्स (इनपुट) {input = "" + input; जबकि (input.length & lt; 8) {input = "0" + इनपुट; } इनपुट = [input.substring (0,4), input.substring (4,8)]; Var आउटपुट = ""; के लिए (इनपुट में var i) {स्विच (इनपुट [i]) {case "0000": output + = 0; टूटना; मामले "0001": आउटपुट + = 1; टूटना; मामले "0010": आउटपुट + = 2; टूटना; मामले "0011": आउटपुट + = 3; टूटना; मामले "0100": आउटपुट + = 4; टूटना; मामले "0101": आउटपुट + = 5; टूटना; मामले "0110": आउटपुट + = 6; टूटना; मामले "0111": आउटपुट + = 7; टूटना; मामले "1000": आउटपुट + = 8; टूटना; मामले "1001": आउटपुट + = 9; टूटना; मामले "1010": आउटपुट + = 'ए'; टूटना; मामले "1011": आउटपुट + = 'बी'; टूटना; मामले "1100": आउटपुट + = 'सी'; टूटना; मामले '1101': आउटपुट + = 'डी'; टूटना; मामले '1110': आउटपुट + = 'ई'; टूटना; मामले '1111': आउटपुट + = 'एफ'; टूटना; }} जबकि (output.charAt (0) == 0 & amp; आउटपुट.लैम्बन & gt; 1) {output = output.substring (1); } वापसी "0x" + आउटपुट; }    
     
     
     अंतर्निहित कार्य का उपयोग करना:  
      ParseInt ('1010101010', 2) .toString (16)

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon.
