Explanation

Placenta previa

  • It occurs when the fertilized ovum drops down and implants in the lower uterine segment.
  • It is the condition when the placenta grows in the lowest part of the uterus and covers the opening to the cervix.
  • It can cause severe bleeding during pregnancy and delivery.
  • It can be diagnosed by Ultrasound scan
  • It can be treated by a c-section (Cesarean delivery) procedure.
  • It is of two types
  1. Complete previa- placenta covers the entire opening of the cervix
  2. Marginal previa- placenta is close to the opening of the cervix but doesn't cover it.

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
