Re: [algogeeks] Re: find duplicate and missing element
this question can be sovled very easily 1.jus sum the given array...x 2.sum the squares of the given array..y 3.now use the AP.n(n+1)/2..for n=100 4.similarly compute n(n+1)(2n+1)/6 for n =100.. Now solve these eqns ...u get the missing and the dupicate.. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.

when arrays are passed as arguments to a function,the starting address of the array is passed like a pointer, thus sizeof(arr)=2..thus 2/2=1..this is the precise reason for always specifying the column length in the definition of function when functions have arrays as one of the arguments..
