| If we have an array of Interger values, find out a sub array
which has a maximum value of the array and start and end
positions of the array..The sub array must be contiguious.
Take the start add to be 4000.
For Ex if we have an array arr[] =
{-1,-2,-5,9,4,3,-6,8,7,6,5,-3}
here the sub array of max would be
{8,7,6,5} coz the sum of max contiguous array is 8+7+6+5 =
26.The start and end position is 4014(8) and 4020(5). | Microsoft | 4 |

repeat for j=i+1 to N do
{
if K[j]<k[min]

| write a program to swap bits in a character and return the value
prototype of function
char fun (char a, charb flag c)
where fun returns a char, char a is a the value char b is
the bit to be changed and flag c is the bit value
for eg: x=fun(45,7,0)
since 45 is 0010 0101
and ow x should contain the value 65 (0110 0101) | Bosch | 1 |
