U can use single walker (from 0 till 31) to convert integers N and M into array of bits, then another walker from i to j to replace values.
for(k=31;k>=0;k++) { N[k]=n & 01; M[k]=m &01; n>>=1; m>>=1; } for(k=i;k<=j;k++) N[k]=M[k]; On Tue, Sep 20, 2011 at 12:44 PM, abhinav gupta <guptaabhinav...@gmail.com>wrote: > I can tell you the logic.Take two arrays N and M, put their bits in > the array. > Now using i and j index replace the value of N[j] to n[i] by M[j] to M[i]. > On Tue, Sep 20, 2011 at 12:33 PM, Ishan Aggarwal < > ishan.aggarwal.1...@gmail.com> wrote: > >> You are given two 32-bit numbers, N and M, and two bit positions, i and >> j.Write a method to set all bits between i and j in N equal to M (e.g., M >> becomes a substring of N located at i and starting at j). >> >> EXAMPLE: >> >> Input: N = 10000000000, M = 10101, i = 2, j = 6 >> >> Output: N = 10001010100 >> >> -- >> Kind Regards >> Ishan Aggarwal >> [image: Aricent Group] >> Presidency Tower-A, M.G.Road,Sector-14 >> Gurgaon,Haryana.122015 INDIA >> Phone : +91-9654602663 >> ishan2.aggar...@aricent.com <puneet.ar...@aricent.com> >> >> -- >> You received this message because you are subscribed to the Google Groups >> "Algorithm Geeks" group. >> To post to this group, send email to algogeeks@googlegroups.com. >> To unsubscribe from this group, send email to >> algogeeks+unsubscr...@googlegroups.com. >> For more options, visit this group at >> http://groups.google.com/group/algogeeks?hl=en. >> > > > > -- > @ |3 # ! /\/ @ \./ > -- @ |3 # ! /\/ @ \./ -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
